SyncToy for Windows XP

If you're like me, you probably have thousands of digital photos and documents that you want to backup or copy to external media. In my case, I copy everything to an external 160GB XIMETA NetDisk for safe keeping. I have used the free version of Allway Sync in the past, and I've had very good results. However, we recently released a handy tool for Windows XP called SyncToy, and based on my few days of experience, it appears to do everything I need. Here are a few of its features:

  • Provides easy and flexible copying, moving, and synchronization of files in different directories

  • Manages multiple sets of directories at the same time

  • Can combine files from two folders in one case, and mimic renames and deletes in another

  • Keeps track of renames to files and will make sure those changes get carried over to the synchronized folder

Configuring SyncToy is as easy as setting up one or more folder pairs and corresponding actions for each pair. For example, I might setup one pair to synchronize changes between two folders (which works both ways) and setup another pair to simply echo changes from one folder to another (echo is the action I use for backup purposes). If you want to get more specific, there are additional options that can be configured.

If you'd like to know what operations SyncToy would perform on your folder pairs, you can run the convenient preview feature. The preview feature analyzes the folders, then tells you what it would do if it ran, but—most importantly—it doesn't actually make any of the changes. This is a great way to get comfortable with the tool before letting it loose on your precious files. And if you want to automatically process your folder pairs, there's even a topic in the help file (lookup Schedule in the index) that explains how to schedule SyncToy to run on a periodic basis.

  1. xml says:

    its nice but it should support the ability to specify hidden network shares because the browse for folder doesnt show them

  2. mswanson says:

    I ran into the same issue, xml. To work around it, I created a new "Network Place" to "My Network Places." This allowed me to access the hidden folder from within SyncToy. Not ideal, but it works.

  3. I saw syncToy but continued with Allway Sync, main due to the autoSyncing.

    Checkout my review of Allway sync at:



  4. If you have wanted to synchronise two folders between machines before but, didn’t want to buy a solution…

  5. Joe says:

    I can’t even get the damn thing to work in Windows XP! I tried installing it twice and when I run the app it never shows its UI. However it is definitely running and eating up over 20000K I might add.

  6. Alex says:

    This is a GREAT tool. I’m so glad this was released. I’ve been looking for something exactly like this as I have both my tablet and my regular laptop and really wanted my documents sync’d!

  7. Flemming says:

    I agree it´s a GREAT tool. I have used it many times over the past week and at a lot of different sites. But it also has it´s glitches, for example the program won´t run in the schedule mode if it´s runned as a different user than the one who is actualy logged on, but hey it´s free…

  8. Nate says:

    Yes, It’s very handy, but it would be great if it could run in the background when I’m not logged in e.g. scheduled jobs.

  9. Matt says:

    A good tool, not great. I would like to see the features of Robocopy integrated into this GUI based tool. A CLI would also be nice for automating tasks with scripting.

  10. spooksman says:

    Since installation on both of my machines, they open the C:Program FilesMicrosoft folder that contains SyncToy folder after every restart – anyone else seen that?


  11. Hey Nate,

    On the Scheduled Jobs, You definitely need to check out Allway Sync (my review here:

    Has multiple options.


  12. smisra says:

    How does one use Sync up short cuts? For example, I want to create a Sync folder on my C: drive called Sync Home. To this folder, I copy shortcuts of the actual folders I want to sync up with (that way I can easily remove these shortcuts when I am no longer working on particular projects). However, on my USB drive, I want SyncToy to figure out that a shortcut availabe on my PC may not be available at the destination, so I want it to actually go into that shortcut and copy all files, perhaps allowing me to configure the "depth" of shortcuts it should follow.

  13. HiggiML says:

    I thought this was a pretty cool util until I found that it doesn’t delete empty subfolders. For example: I have Pics1, Pics2 & Pics3. I decide I want to move them under a folder called PICS so I end up with PICSPics1, PICSPics2 & PICSPics3. After a sync, the destination drive will have the PICSPicsX folders with all my files but the original PicsX folders will remain, albeit empty. Maybe I’m missing something but that’s a big booboo.

  14. HiggiML says:

    Oh by the way, Nate, I’ve successfully scheduled SyncToy to run via XP’s Scheduled Tasks while I’m not logged on. That seems to work fine. My *only* gripe is the actualy folder structure synchronization. Good luck.

  15. Moonbutt says:

    Why dont you just use the latest version of Robocopy?? I’ve found it to be the lightest and quickest of all the sync and file tools available.

    If you create a simple bat file with all the switches you can easily use it in a schedule.

  16. Tommy says:

    I thought I could use SyncToy to ECHO the files in my Documents folder to the CD-RW drive folder (for backup purposes).

    No dice.

  17. Jason says:

    Does anyone know if you can install synctoy on both machines that are to be kept in sync. That way I can run it from which ever machine I’m on.

    I was concerned the SyncToyDirPairs.bin file it creates will get copied and overwrite the SyncToyDirPairs.bin on the other machine.

  18. MikeLaughlin says:

    It is very cool but won’t delete empty folders. I have two computers with lots of AVI files in many folders. When I delete all the AVIs in folder A and move them to folder B on one computer the SyncToy won’t delete folder A on the other computer. I have tried invane and it just won’t work. Major flaw!

  19. Lee Keels says:

    Can’t get this to even install since I have .Net framework 2.0 installed.  It says it requires a lower version number.

  20. Shawn says:

    Not being able to delete directories in echo mode makes Synctoy pretty much useless for me.  Who the hell wants a bunch of empty directories laying around?

  21. Reyna says:

    Hi. Thanks for the feedback on SyncToy.

    Deleting empty directories – this was a bigger task than we had time for in v1.0. It’s on the feature list for v2.0. For 1.0, we based our decision to not to the work to delete empty directories on how other sync’ing programs like RoboCopy behave.

    SyncToy v1.x requires the .Net Framework 1.1. It works to have both versions of the Framework installed – when I tested it, I could install SyncToy as long as fx1.1 was installed, then I added fx2.0 for the other apps that require it.

    Thanks for the suggestions. We’re definitely listening to what users are saying, although we cannot promise that every request will make it into the next release.


  22. Doog says:

    Hi, I’ve been trying for some time to get SyncToy to run as a scheduled task.

    It works great when I’m logged in, but I share my computer with others, and I really want it to run for them too. Am I missing a trick here? HiggiML above says it works fine…but gives no details. Can anyone help?

  23. Rex says:

    I would like to know if I can use this to backup from multiple PCs on a network to one external USB 2.0 drive on one of the PCs??

  24. Rex says:

    I could now with version 1.2 access an external drive as my backup file. But I cannot get the scheduled run to work. Is there something special I need to do other than the instructions in Help??

  25. jfvi says:

    i can’t have it to work within the task manager

    "C:Program FilesMicrosoftSyncToySyncToy.exe" -R

    the respond in the log file is :

    SYNC: 04/22/2006 00:30:04:035: Beginning SyncToy run for all folder pairs.

    SYNC: 04/22/2006 00:30:04:316: *** Exception: It is invalid to show a modal dialog or form when the application is not running in UserInteractive mode. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

  26. bwana says:

    how to make it run silently?

    or as a service so that it wirks even when you are not logged in? (e.g. screen saver comes on and pc goes into standby)

  27. jab says:

    I also cannot get SyncToy to run as a scheduled task.  I created a new user account "backup" that has a password so that it can run scheduled jobs.  However, SyncToy never seems to actually run.  The log says it is starting, but nothing is copied and the job finishes too quickly.

  28. grrr says:

    The download page for the .NET Framework 1.1 gives a 404 when it redirects to get the package.  As others have noted, the 2.0 framework won’t do it for this installer.

    Why must Microsoft break its websites this way? 🙁

  29. Stephen says:

    This program looked very promising but unfortunately turned out to be a damp squib when discovering that it does not delete empty folders. After having done a couple of days work, moving, creating and deleting files and folders etc. The destination ends up a complete mess of empty folders in amongst the "live" ones. This should have been a fundamental requirement not an afterthought.

  30. Frank says:

    I used it to back up large amounts of data from an NDAS device to another computer. During that week, people have rearranged their files. Now, when I compare the backup to the orginal files, it appears that Synctoy just kept making backups of the new or rearranged files, but NOT deleting them from the backup. This solution is completely useless.

    I decided to run it at home so I can backup the My Documents folder. I also had the same person. We are both using Echo to copy the contents of the My Documents folder to an external HDD. Guess what? after a week or so of doing this, when I right click on My Documents and look to see the file size and the amount of files and directories, it is VERY different than the one of the backup HDD. If it was truely echoing data, they should be extactly the same.

    As far as I can tell, this program is usless for backing up data. I will definitely recommend people not use it.

  31. Mark Greaves says:

    A problem I have just discivered is that SyncToy backs up new sub folders of directories you have chosen not to copy.

    E.g. I had set up Synch Toy to copy stuff from My Documents to a second hard disk as a scheduled task.  The second disk is an older one I have just installed and is only 14 Gb but useful for document backup.  I set SynchToy to NOT copy the My Music sub folder since the files in here would have filled the second disk.  This worked fine until I ripped a new CD there by creating a new sub folder under My Music.  This new sub folder was copied over to the second disk even though the parent My Music was flagged as not to be copied.

    I don’t really want to tweak the settings of SynchToy every time I add some music.  ANy body know a way round this?

  32. John says:

    UGH, how did the guy above manage to get it to run as a scheduled task without being logged in?  ANYONE?????

  33. Mark Greaves says:

    My scheduled task of Sync Toy only runs when I am logged in.  I have not tried to create a task that runs when I am not logged in.

    Sorry for the confusion. :-$

  34. DavidB says:

    I have the same problem as Spooks earlier post – the Synctoy folder opens after every reboot.  Has anyone got a solution for this?

  35. Tom Croft says:

    I’m happy with SyncToy but, as usual, there’s something missing. The fact that it doesn’t delete folders on the RHS is a serions shortcoming. How can it be called a SYNC? if it doesn’t smart delete. I have never been able to understand why microsoft’s "ActiveSync" (For PDA’s) isn’t expanded to allow for PC-PC as well as PC-PDA sync’ing.  Now that would be REALLY handy.

  36. fredandbarney says:

    Would be nice if it was recompiled under the dotnet 2.0 environment. it only works with 1.1

  37. Aderbal says:

    Is possible change the SyncToyDirPairs to diferent path. I would like to keep this configuration in my network drive. I think the directory C:MyDocuments my users may clear this file ???

    Thanks a lot.

  38. wim says:

    before installing synctoy and nswering "yes"to installing framework, a version of framework is installed after which Synctoy again requires the installation of framework.

    Fortunately there is Google to find the above answer to this problem here. MS knowledgebase did not help me. Anyway reading about more problems with synctoy I think it is not wise to use it.

  39. madh says:

    Each time I run Syntoy, I get a dialog that says "Syctoy is unable to determine if other instances of SyncToy are running, possibly because perfmon counters are turned off for some components. Is this the only instance of SyncToy currently running?" Yes  No.

    Very annoying.

  40. AndyB says:

    I like it, its nice and pretty and seems easy to use.

    I’d like to offer 2 items of feedback that I thought the tool lacked. I personally think these are quite major points, otherwise its great.

    1. I cannot exclude files. eg, if i want to sync a pictures directory, I do not want it to copy thumbs.db for example.

    2. I would greatly prefer it to exclude subdirectories of subdirectories I uncheck in the options dialog. The poster who complained about it syncing subdirs of My Music when new directories are added is right -it should be made to remember the root directory and exclude it and all its subdirs, unless a subdir is explicitly included. The GUI tree needs to be able to do this – uncheck a directory and all its subdirs get unchecked automatically.

  41. Sanjeev says:

    I love it too…

    The only issue I had using it was while Syncing my PC to a flashdrive. One of the files was bigger than the free space available on flashdrive and it would not replace the old file. The total space available (old file + free space) was more than the new file replacing it.

    Please let me know if there is someway of fixing this issue.

  42. Clint Kirk says:

    Nice tool, but not so keen on the way it’s been implemented. Firstly, it creates a useless (to the user) folder called SyncToyData in "My Documents". Bad style. It should have been a subdirectory of %APPDATA%Microsoft.

    Secondly, it creates a hidden (unless, like me, you’ve set up Explorer to show hidden files) file called SyncToyDirectoryId.txt in each folder of a folder pair. Why on earth does it have to do that? That is intrusive, offensive behaviour and a total show-stopper for me! It was hoping to use it to synchronize my Favorites folder on my desktop at work with my laptop, then take the laptop home and syncronize my laptop’s Favorites folder with my home desktop. I cannot do that, because the desktop and the laptop both have SyncToy installed and they both want to write different numbers in their copies of SyncToyDirectoryId.txt of my laptop’s Favorites folder. What a pity, it could have been a very useful tool if only it had kept its own private data-keeping private.

  43. n22d3a says:

    I have the same problem as Spooks and DavidB earlier post – the Synctoy folder opens after every reboot.  Has anyone got a solution for this?

  44. Jason Cox says:

    I have to side with Clint Kirk… But for different reasons.  I want to have multiple users sync a networked folder to an external device.  I noticied that failing to delete the file SynctoydirectoryID.txt causes the files not to replicate correctly.  While I think the file in the directory is poor form, being able to select a different file name with a registry key may be a quick and dirty solution for those of us wanting to use it now.  Also a warning when first using the product would be nice.

    The other thing that needs improvement is permission for non-admin users.  Sure you can raise the .Net trust for Synctoy but the installation should at least ask to do it for you.

  45. Shawn says:

    Not being able to delete directories kills it for me.  Who the heck wants a million empty directories lying around anways?  And can you truly call it synchronization if it doesn’t?

    Spend the $20.00 and buy the Allwaysync Pro.  Its worth it in my opinion.

  46. John says:

    I have SyncToy set up to synchronize from my laptop to desktop with the laptop as the left folder.  After every synchronize my laptop is littered with 200k syntoy files – what is going on?

    Unless this is a setting that needs to be switched off it totally ruins SyncToy.

  47. Chris A says:

    Picked this up after a bit of searching…


    SyncToy does not provide a user interface to schedule folder pairs to run at designated times. However, there is a method to schedule tasks using the Microsoft© Windows© operating system.

    To schedule a task using the operating system:

    1. From the Start menu, select All Programs – Accessories – System Tools – Scheduled Tasks.

    2. Select Add scheduled task to start the Scheduled Task Wizard. You will see a list of possible programs to run.

    3. SyncToy may appear as an option in the list. If SyncToy does not appear in the list, click Browse and go find it.

    4. The wizard will next prompt you to enter how often you want to run the scheduled SyncToy (for example, daily, weekly, et cetera). Select a frequency.

    5. The next page asks when to start the task. Select a start time.

    6. The next page asks for the user name and password to run the program under. Enter your user name and password.

    7. The final page contains an option to open the properties dialog when the wizard ends. Select this checkbox.

    8. Modify the Run textbox to include the –R command line option. –R all by itself will run all folder pairs that are active for run all. If you want to run just a single folder pair, add –R“My Pair” to the end of the command line. Note: there is a space before the hyphen but not one after the R. If the folder pair name contains a space, surround it with quotation marks, as the example above shows. For another example, assume that SyncToy is in the folder named C:My Folder and that you want to run a folder pair named "My folder pair." Enter the command line as follows, including the quotation marks: "C:My FolderSyncToy.exe" -R"My folder pair." Note that there are two sets of quotation marks in this case: one is around the path to the SyncToy program file and the other surrounds the folder pair name.

  48. oldfogey says:

    To people reading this page..

     If you are still having difficulty running SyncToy when not logged in, the fix is fairly simple.  You are required to have a password on the user account from which Synctoy acquires its permissions.  Without a password, the Account must be logged in.  With a password, make sure the ‘Run  Only when logged in is checked, click Apply, and enter your password.  That should do it.


  49. mach7 says:

    I have noticed that SyncToy keeps overwriting some of the files I have not modified every time I run the tool. Have you experienced that? I have looked everywhere, but I have not found a solution. It is a problem when one of those files is very large. I am using version

  50. Matthew Tippett says:

    Another potential problem with SyncToy is that if a file is changed on both the LHS and the RHS between syncs, it sems to just overwrite with the most recently modified rather than alerting you to the fact that it has changed on both sides and that you need to do something mannually to merge the file.

    Another really useful faeture would be to have the option to change the direction of an overwrite on a manual basis per file.

    Reyna’s response (Monday, March 27, 2006 6:24 PM)to HiggiML (Saturday, February 04, 2006 7:25 PM) and MikeLaughlin (Wednesday, March 22, 2006 1:34 AM)comments was interesting, any update on that?

    If these three things were able to be written itno wynctoy – it would be very useful. Would people recommend Allway Sync as the best GUI syncer that won’t make an overwrite where changes have been made on both sides without warning you?

  51. Markus says:

    !SOLVE! the problem of userinteractive mode:

    Watch at, a user has developed a console wrapper for the synctoy.dll. Thus, you don’t have to start the frontend for the sync-prozess and thus, you won’t get the error anymore. (search for synctoy)

    Need to say, that you have to compile it, it’s just sourcecode…

  52. Your_mum_Quake says:

    MCE file back-up/synchronisation:

    SyncToy – does not run properly on MCE PC (unable to determine if other instances of SyncToy are running) so have it running on an XP PC instead which has a schedule to regularly wake from sleep state – if it’s asleep (normally hibernation) and then wake up the MCE PC from its sleep state (normally hibernation), wait 40 seconds and then synchronise (echo) the data files (Music, Pictures and video) – ignoring the Temp file/dir in Record TV.

    The XP PC only has one account with no password but XP by default can not add a scheduled task running under a local account without a password. Also, XP Sync toy does not appear to run properly under another account (with a password) that is not logged on! So need to disable security policy: ‘Limit local account use of blank passwords to console logon only’ – now you can add a scheduled task under the local account without a password!

  53. With over 33,000 total views, my August 9, 2005 announcement about the release of SyncToy is one of my

  54. Sean Kelley says:

    SyncToy v1.4 shipped today and you can download the new bits at the link below:

    In addition to some minor bug fixes, we focused on the following tasks for this release:

    ·         Vista Compatibility

    ·         .NET Framework 2.0 Compatibility

  55. your_mum_quake says:


    Having upgraded to 1.4 fixes the ‘unable to determine if other instances of SyncToy are running’ error!

    However – after completing a successful scheduled task run SyncToy crashes! Have sent M$ the crash dump. SyncToy does run OK if ran manually and will close OK without crashing – it is only when run as a scheduled task will SyncToy crash upon closing after a successful run!

  56. That’s odd.  I did not encounter the problem with scheduled task as you mentioned.

  57. Ace says:

    SyncToy opens an annoying Explorer window on every startup and won’t uninstall. It has even messed up System Restore so that there seems to be no way to get rid of it.

  58. Mike Cline says:

    I have been using SyncToy to backup my hard drive with pretty good success. But today I decided I wanted to exclude one large directory from the backup.  The GUI is there for excluding subdirectories, but it seems to completely ignore it.  I unchecked the directory that I was interested in excluding from the backup, but SyncToy continued to include that subdir in the synchronization.  Why?

  59. Polski says:

    Agree with Mike Cline above – just installed SyncToy 1.4 on my freshly installed XP box with .Net 2.0 only (no 1.1). I can exclude entire subfolders but it ignores this setting and copies them anyway. Please fix this glaring mistake – it is making SyncToy 1.4 unusable  at the moment.

  60. Zino says:

    In echo mode it doesn’t delete files in the right directory which are deleted in the left one.

  61. Richard Bates says:

    Note that excluding a subfolder only excludes files within the subfolder. To exclude nested subfolders you still have to untick them yourself. You can right-click on a subfolder to have SyncToy do this for you.

    Err… yes we are doing this. It still does not exclude them from any Sync actions.

  63. Tim says:

    Sync toy is great, (here it comes) but it’s failing when run as a scheduled task. It’s failing with the exit code 0xe0434f4d, and I have the following errors in the Event Viewer: "The COM+ Event System failed to create an instance of the subscriber partition" and "EventType clr20r3, P1 synctoy.exe, P2, P3 453f990b, P4, P5, P6 4333aefa, P7 3d21, P8 ee, P9 system.invalidoperationexception, P10 NIL."

  64. Damien says:

    Synctoy 1.4 would be great if the exclude folders would work.

    I try to back up my My Documents folder, without the 2 folders My Music and My Pictures (as well as their sub-folders).

    And every time, those 2 folders and their subfolders are copied…

  65. Dave Doherty says:

    Why oh why won’t MS do a file exclude box? When working with photos I’m always having to manually uncheck some .ini file in each of my 100’s of folders.

    Is there some way to do it in the "include" box maybe with with a minus sign???

    This would be a great tool if for only this one thing (for me).


  66. Viperguy says:

    I second most of the remarks here.  The tool is a good one for casual users that want to copy photos etc to multiple locations but has serious limitations for advanced users.  In the server world, synchronization means just that.  After a sync the target directory is identical to the source regardless of what was moved/added/deleted or when.  This tool will not delete directories and will not create empty directories as well as a few other limitations.  It’s a FILE based copy utility rather than a DIRECTORY based sync tool.

    **Also, for any advanced user the need to save the setup (directory pair and configs) is critical to ensure that the PC admin or user never looses all of the work of setting up dozens of directory pairs.  Other sync utitilies IE All ways allows you to save the profile and then use it anywhere, reinstall, rebuild the PC, whatever and instantly recover the synch configs.  SyncToy?????  So when I rebuild my PC I loose all the synch configs and start over?  Sync’Toy’ is the correct name.  Not bashing the product.  Great for casual users as I said, but a toy at best

  67. cullwock says:

    SyncToy 1.4 does have some serious problems. I tried to sync two directories, and it suggested deleting about 3,000 files from the local side, even though exactly the same files were on the remote one, in exactly the same directories, with exactly the same date and time stamps and sizes. I have no clue why… Then, when I run the whole thing again, it copies them back over! Strange thing is, though, when I choose to echo rather than synchronize, it doesn’t complain at all… Weird.

  68. chris brace says:

    I have a problem using synctoy on several machines to keep a series of copies of my data. The tool keeps ignoring lots of files and folders when they DO need to be copied. If i run it on an individual folder it works fine. If I try a whole group of folders and subfolders it seems to ignore stuff at random.

    Any ideas?


  69. chris brace says:

    Ok, I think I may have found a fix. I have deleted all the SyncToyDirectoryId.txt files and rerun the sync job and that appears to be working properly. My guess is that the SyncToyDirectoryId.txt files somehow because I’m using synctoy on several machines. It is just a guess though!

    Seems a messy way to do it, maybe it’s an attempt to make it run faster but I’d prefer it to sct as if it were the first time every time, it seems to work then!


  70. Harlan says:

    I have the problem with autorun; I also have the problems mentioned with exclusions and matching multiple devices.  There is no option to *ignore* previous information and simply do a full check on the files.  This program is not a proper "utility"; it’s more like a throwaway experiment someone did as a training exercise.  If they’re not going to support it properly, at least post the source somewhere and let people tweak it themselves.

  71. Dan says:

    i tried to echo to my usb hard disk.  i was expecting it to delete files on it that did not exist in the specified folders on the "left" its tedious to go through and manually delete files on 2 drives.

  72. Jerry says:

    I use Synctoy to quickly sync files from home, laptop, work PCs using USB stick.  I merely sync entire My Documents folder.  Trouble is that Synctoy files are stored in My Documents folder, which causes errors.  Sometimes Synctoy ends up looking for folder pairs from another PC.  Should be a way to direct where Synctoy stores these operating files, i.e. not in My Documents.  

  73. Derek says:

    Does anyone know where the synctoy settings are kept such that you could copy the preconfigured pairs from one machine to another?

  74. Jim says:

    In Echo mode, it doesn’t work with folders (neither creating new nor deleting old).

  75. Mike says:

    In Echo mode the files on the left are not deleted on the right.  It only works with updating or new files.  Overwrites and new files work fine though.

  76. Hugo says:

    I use it for Archive (using Contribute which means I can delete older versions of files on my live disc knowing they’ll be on the archive copy) and Sync laptop to desktop.

    Still room for improvement (eg when a folder+subfolders are marked for exclusion, excluding new subfolders; putting deleted "old versions" somewhere specific, long path names still cause errors, Update on File Change (with Network Drive attach detected)) but generally very good for a free tool, and avoids all the problems of Briefcase.

  77. Allan Olesen says:

    This tool seems to be intended for keeping two folders in sync in a situation where user changes may happen in both folders.

    Such a tool must ALWAYS warn the user if a file have changed in both folders since last sync, since the tool have no way of knowing which (if not both) version contains changes to be kept. SyncToy fails at this.

    Until this is corrected, the tool is more Toy than Sync.

  78. Greg says:

    This is for anyone that is still having problems with v1.2.

    As noted above, for v1.2, the configuration files/pairs are stored in “My DocumentsSyncToyData”, so you can copy these back to a new installation.

    Also thanks to Chris Martin at for coming up with a solution for the dreaded “SyncToy is unable to determine if other instances of SyncToy are running” problem.

    It turns out the perfc009.dat was missing from my “c:windowssystem32” directory. I just copied the file from an old XP installation,and just to be sure, I copied any file named "perf*.*". Now SyncToy starts up without the error message. BTW, when I was getting the error message, the Performance/System Monitor wouldn’t work either, but now it’s running.

    I’m able to run SyncToy in the Task Scheduler whether I’m logged on or not, I’m using XP Pro with multiple accounts, just followed the directions, made sure the “Run As” was correctly filled in, and the password entered, and the “Run only if logged on” was unchecked. Everything works within acceptable parameters, not perfect, but acceptable for a free program.

  79. Mohit Datta says:

    I love this tool. I think the design team made the right decisions in keeping it simple. The target audience is well served by this tool.

    I’m sure they’ll fix whatever bugs exist in the 2.0 version. My only feature request is the ability to filter out all subfolders recursively, if you deselect a folder.

  80. Dave says:


    Good simple tool, however it lacks an important feature (either that or I can’t find it), which is excluding files during a backup.

    I’m trying to use SyncToy in conjunction with an autorun.inf on my USB key to ‘echo’ the contents of my FireFox profile on my HD to the profile folder of PortableFirefox on my USB key when I plug the thing in. The problem is if FireFox is running already, it creates a file called parent.lock which you cannot copy because it’s in use.

    Is there a way to tell SyncToy to skip that file?


  81. Rachel says:

    Hi, I have a fairly unsual setup with a NAS that has my "My Documents" folder on it, and each PC on the network has a login for me with the My Documents folder pointing to the NAS location. That way when I log onto whatever PC, my My Documents is always available.

    I am finding the  The huge gotcha with SyncToy is the storage of the logfile and pair informaiton in the My Documents folder, which is on the NAS (although the .exe installed into my local settings folder, which is local to each PC. Bizarre location if you ask me!). But having the pairs in the My Docs location means that when I run SyncToy on any PC, it can’t have local pairs just for that PC unless I do a complicated set of turning ons and turning off pairs before I run it each time.

    SyncToy needs to store its settings and logs files somewhere more approriate, like the local settings folder! Or even let it be a user configurable option.

    I also dislike intensely the way if files are changed in both locations it just silently deletes the older one. Hardly a sync tool at that point, is it??

    Anyone else wrestling with similar issues?


  82. Henry Nguyen says:

    I do like this program very much for its simplicity. However it keeps create a folder names _SYNCAPP every time a new sync job is started.

    Not sure if this has anything to do with the previously uninstalled Allways Sync.

  83. Henry Nguyen says:

    Sorry guys. I just discoved that Allways Sync created these hidden folders originally. Just have to manually delete them all.


  84. Ed says:

    I love SyncToy and find it a very useful tool except for two things. Not deleting the empty directories can be a problem. The biggest problem though is that if I uncheck copy folder and all subfolders SyncToy will copy new subfolders that are created in a folder. I unchecked that SyncToy should copy temp internet folders but since new ones are created all the time it will start to back up the new ones. The biggest problem with this is that SyncToy has a major problem with backing up file and folder paths that are too long. The tem internet folder seems too often create files in this category. If the name is too long SyncToy will fail. I run the backup automatically and SyncToy does not inform you of the failure in auto mode. Do you know if these problems will be fixed in version 2 and about when version 2 will come out?

  85. camtarn says:

    Awesome tool – I’ve used Unison for this sort of thing before, but I find the SyncToy interface much more intuitive and usable for the simple tasks I’m using it for. Thanks to the SyncToy dev team!

    My only big feature wish is that it could sync over a network, using FTP, SFTP, WebDAV etc, so that I could use it to automatically sync my local copy of a website with my online copy, and send backups of my files to my webhost.  However, it’s still great without this feature.

    More worrying are the reports I’ve seen above of silently overwriting older files – this probably should be fixed at some point. Until it is, I guess I just need to keep that in mind, and sync often.

  86. SaxDaddy says:

    I like the concept of SyncToy but I _had_ an issue that I now can’t seem to duplicate…

    I installed v1.4 and rather than use the task scheduler I decided to create a shortcut in my userprofile’s startup group so that it ran when only I logged on.  The short cut called synctoy.exe (fully qualified directory with correctly syntacted quotes) and the -R option.  ST crashed every time and deleted my folder pair data after each crash.

    I decided to try the task scheduler and it worked!  No crash and no deleted folder paris.  That’s great but now I can’t recreate the crash.  I guess that’s good but:

    1. Why did it crash in the first place

    2. Why does it delete folder pair data after a crash.  Log files only show successful syncs and I didn’t check to see if the BIN files were deleted.  

    Just curious…

  87. Larry Stone says:

    This tool was the solution to two needs for me.

    1. I needed a way to copy backup files (.bkf) created by NTBackup from where they are stored to a removable USB drive for off-site storage. The backup job is scripted. Each file has a unique name based on date/time, and the oldest files are periodically deleted. SyncToy in echo mode is a great solution for making the removable drive a mirror of the server’s backup folder. P.S: In this instance I’m running SyncToy 1.4 on Server 2003!

    2. Workstation users were storing mission critical data locally on their PCs. Created each their own location on a network share, worked with each user to determine the critical data stored locally, and created folder pairs running in echo mode. Network share is backed up nightly. Users run SyncToy before shutting down each night.

    Observation: SyncToy is a "profile specific" application. When configured as a scheduled task, the account it runs under must have a profile on the machine and it must be configured with the folder pairs. I have a special account (password never expires) for running scheduled tasks. I cannot configure SyncToy folder pairs while logged on as Administrator and then run SyncToy as a scheduled task under the special account and expect it to sync the folder pairs that are stored in the Administrator’s profile.

  88. Larry Stone says:

    Running as a scheduled task does not perform as I thought. If you are not logged on with the user account that the scheduled task is running under then it will fail. This makes it unsuitable for what I need. I need a regular user (the owner of the business who carries the removable drive home as an off-site storage of server backup) to be able to launch the job from his desktop after connecting the USB drive to the server.

    Since the VB code for overcoming this problem is available at then I must assume that it would be an easy feature to enable for the people who create and maintian this tool.

    I am not a programmer but have created a compiled program that automates running NTBackup. It runs with a UI if no command line arguments are passed, else no UI. It will run as a scheduled task with no one logged on at the console and it must retrieve data from the profile of the user account that it runs under. No problemo.

    For SyncToy to be so close to a needed solution but after 2 days realizing that it simply won’t work it very disappointing.

  89. Falcon says:

    Has anyone managed to completely uninstall SyncToy? I tried upgrading to the latest version but keep getting a message that Windows is unable to uninstall the older version of SyncToy in WinXP. Also, only one Administrator is able to access and use the program when it was first installed. It would be good if other users could get to use the utility too. Please reply if you know how to completely clean this thing off a machine.

  90. Nicole says:

    I am also wanting to know the trick on how to completely clean my windows XP machine of sync toy.  If anyone has a clue, please let me know.  

  91. Yan says:

    I don’t know if anyone else has the same problem. Basically, I tried to sync a folder to another, with the source folder full while target folder empty. So Synctoy should copy all subfolders/files to the target one. But it consistently miss one file every time I try it. If I run "preview" a couple times then the left-out file will eventually pop out to let you copy it to the target folder. Any ideas what’s going on?

  92. Yan says:

    Just realized that SyncToy has problem dealing with files that have long filenames/suffix. I truncated the suffix of that left-out file and now it seems to work.

    Sync toy has problem of stripping parts of metadata from my Canon 5D and 10d files.

I thought this would be a great way to back up to my laptop, but with this glitch I am affraid to let this thing handle my important files.

    Anyone had similar problems?

  96. KK says:

    Love it…just requires a few bug fixes and a few enhancements. Not sure if this has been mentioned in this thread already, but one thing I noticed in the Echo mode was when I rename a source folder that has sub-folders, and try to Sync, SyncToy hangs. CPU usage kicks to nearly 100% and nothing seems to happen. I recover by stopping synching. Once I renamed the folder in source back to original, there was no problem synching.

    I use

  97. Cleveland, Ohio says:

    I’ve used SyncToy 1.4 with no problems in the past.  All I do is ECHO from the desktop to the flash drive.  However, recently I find that SyncToy is not creating any new folders (which obviously means the new files in those folders don’t get copied to the flash drive).  I tried creating the folders on the flash drive manually using Windows Explorer, but I get a "cannot create folder" error message.  

  98. Cleveland, Ohio says:

    I forgot to ask at the bottom of the message above – does anyone have a solution to this problem?

  99. owen says:

    I have been using SyncToy to setup automated backup for clients to their external backup drives. I’ve worked around the drive naming issue if using more than one external USB drive with the excellent freeware, USBDLM  A simple .ini file on each drives assures its drive letter.  Combined with SyncToy, I can have the entire Docs.Sets directory backed up to two separate drives, allowing for onsite/offsite backup with easy swapping.  

     The ONLY thing breaking this completely free solution is SyncToy’s difficulty with long filenames in the Temporary Internet Files directory.  The primary culprit of these creations seems to be Kodak’s Easy Share software.  I wrote them, but I’m not holding my breath…  I have setup an automated run of cleanmgr using the /sagerun:50 and /sageset:50 commands, but this doesn’t always clear out the temp internet files directory.  So I guess there are TWO problems.

    1) SyncToy’s inability to handle the long filenames and failing with little to no warning


    2) Cleanmgr failing to clear out the tempinternetfiles directory prior to the scheduled backups.  

    Any ideas and reco’s from the crowd here?


  100. nick says:

    I’m trying to echo my PC files and folders to an external backup hard drive. Simply want whatever changes I make on my PC to be mirrored on the external drive. SyncToy got very confused when I renamed one of my subfolders. SyncToy reports that all the renames failed. So SyncToy is not so good if you re-organise your folders (something I do quite often)

    Running v1.4 on XP Pro SP2 (local & remote).  Do a run and it indicates it was successful.  Then do a preview and MANY more files appear (I’m attempting to back up approx 20GB).  I can manually check them one by one but what’s the use?  Even if I do, what files are being missed?  This program is a disaster in waiting.

    I’m also seeing the bug with empty folders being left behind.

  103. Tim says:

    Sometimes, after I have run Synctoy, I try to open the recently sync’d EXCEL file and instead of opening it, Excel states that it is in an unrecognizable format.  Anyone else have a problem/fix for this?


  104. Rodney Franks says:

    I have had problems with SyncToy hanging.

    I would try and synchronise ‘my documents’ folder and it would work a couple of times and then today whilst I was using it, both the  preview or run , would hang on the step "loading saved information for C: …". So after waiting for 20minutes i eventually closed synctoy window which left a synctoy process running which i also had to kill.

    The way i solved the problem was to delete the bin files in the folder

    "C:Documents and SettingsrodneyMy DocumentsSyncToyData"

    Be careful not to delete the SyncToyDirPairs.bin file though which seems to contain the list of ‘Folder Pairs’.

    After deleting the *.bin files (there is a left and a right file associated with each folder pair) it now works perfectly !!!

  105. David Britton says:

    I had SyncToy running at one point.  Then it ceased and began trying to execute an install but was unable to finish (what, I don’t know.)  I decided to reinstall but am not permitted to.  The dialog informs me that the install is unable to continue due to potentially unsafe material having been downloaded and that I must get the administrator (me) to change the installation process to "basic".  Has something gone awry on my machine that I can no longer execute .msi files?  Anyone?

  106. Andrew says:

    Cheers for the tip Rodney – that’s exactly the same hanging problem I’m having with SyncToy

    I have a networked backup machine, and until SyncToy arrived I had to delete the old backup and copy everything over again each time – very time consuming! Now I just echo everything.

    I find that the "loading saved information for C: …" etc message only appears if the folder pair being echoed has lots of files – and it only fails on the 2nd time round, after the first run completed OK (i.e. there is no relevant .bin file to load on the 1st time round). Might it be something to do with the size of the .bin file? Certainly the SyncToy task is eating lots of RAM when it hangs, I’ve seen approx 400MB and 700MB.

    Deleting the .bin files has two disadvantages. Firstly, the speed of the sync run will be slower, as SyncToy will reconstruct the directory/file structure in full each time.  Secondly, any files you’ve deleted since the last backup will not be deleted from the backup next time SyncToy is run, as (if I understand correctly) the .bin file contains information as to what files were and weren’t there (and where they were) at the last run.

    I can live with the ‘not deleting empty folders’ bug as they don’t take up space in the backup, but not deleting files from the backup that I have deleted in the original will be a problem, as the backup will slowly grow. I guess I’ll just have to manually delete the whole backup every so often.

    Another solution to this problem is to reduce the number of files in the folder pair (go from one folder pair D: to multiple folder pairs D:Documents, D:Pictures, D:Software, D:Video etc) but it’s inconvenient to say the least, as I have about 20 folders in my D (data) drive. (I wouldn’t use D: and exclude only say D:Pictures as it falls over the bug where new folders created in the excluded D:Pictures are not excluded.)

    Also – some of the problems others have found may be due to files being "open" at the time – you can’t expect SyncToy to deal with a file correctly if it is open for editing…

  108. Rennie says:

    I cannot uninstall my SyncToy using the ADD/REMOVE programs.

    Any ideas?

  109. Wim says:

    It is quite obvious that "echo"does not delete in the right folder how can this program be released?

    Free ok, but instead of reliable backups you get a mess. Beware of this program and try something else.

  110. hola4 says:

    "Each time I run Syntoy, I get a dialog that says "Syctoy is unable to determine if other instances of SyncToy are running, possibly because perfmon counters are turned off for some components. Is this the only instance of SyncToy currently running?" Yes  No.

    Very annoying."


    Enabling that perf counter for the PerfProc.Dll addresses this issue and

    enables SyncToy to run.

    We will take a look at alternative means of determining whether SyncToy is

    already running for possible inclusion in a future release.

    For those interested, the registry entry for PerfProc is:


    As you might expect, the Disable Performance Counteres REG_DWORD = 0 for not

    disabled and = 1 for disabled.

    I hope this helps.

    I just loaded SyncToy on my XP system and was looking to Sync up my My Documents folder with a folder on my network as it’s been 4 months since I last backed it up. (my bad)

    I select the folders and run the preview. It’s taking forever so I kill it and go back to my My Documents folder and it’s empty. 15GB worth of work lost because I kill a job?

    Stay away for this monster.

    Does anybody knows how to run SyncToy automaticaly? It runs manualy fine but when I scheduled a task – no action.

  115. csinacnc says:

    Being able to filter by modification date is imperative.

    The preview mode should show the from on one side and the to on the other, with arrows or color codes to show which direction files are moving.

    You must be very viligent when syncin’ between different computers. If the computer clock don’t agree, you can and will wipe out new data with old data. (This happened to be around daylight savings time adjustment

  116. David Mc says:

    Hi, I think SyncToy needs a LOT of work.  Here are a few things I’ve noticed after installing it to back up my DFS (Distributed File System) to a local hard drive on my new Vista Ultimate machine with a 500GB drive that for the first time has allowed me to shadow my whole DFS to a single drive.

    1. It won’t read any file with a Tilde (~) in the file name!!  I can’t beleive nobody else has noticed this.  Tilde’s in file names are extremely common.  MS Operatings systems, apps, and developer tools CD’s generally all have files that include tilde’s (Win 2K, 2K3, XP, MSVS 6,2003,2008, MapPoint 2002, and many more) and I store those CD’s on my DFS (so that I never need to use install CD’s, the computers point to the DFS is their install source and any add/remove features action reads from there, a common practice).  This is a HUGE problem.  The Windows OS’s all accept tilde’s in the file names–why on earth won’t this program?

    2. When I backup (echo) my DFS, it simply does not remove files that are no longer present!  Do I have to have performed the delete operation from the installed location of SyncToy for it to recognize that they are now missing or what?  (I don’t just mean the folders remain, which is also a bad feature as has been widely pointed out here, but the files themselves remain.)  I’ve run the echo several times and the files stubornly persist even though they have been deleted from the “Left” folder for weeks.  

    3. Long file names are accomodated by the Windows operating systems with no problems, yet several hundred files are not readable by SyncToy because the paths are too long.  I can’t rename the paths because they are intall CD’s. That SyncToy won’t accept the same long paths and Windows (98SE, ME, 2K, XP, 2K3, Vista) will is a tragic flaw.

    4. Numerous “access denied” errors result (seemingly randomly) during synching (echo).  I can browse them in Notepad or whatever, and the permissions are totally permissive (Everyone Full Control).  What is causing this?  Other backup tools encounter no such problems.  Why are different files doing it each time?  Mysterious…

    From what I’ve seen, the “Toy” part of the name is very apt, and no valuable data should ever be entrusted to the program.  A better idea would be to simply perform a file copy to the shadow directory once in a while.  I’m also going to look at the inherrant features of DFS for creating a shadow DFS, but I back in the Win2K days when I tried it last that was problematic.

    Anyway, SyncToy developers should throw a few files with tilde’s in the name into their test file set, and use some very long file paths as well.

  117. M. E. Kabay says:

    Has anyone run into the message “Exception during run: The even log file is full”?

    The synchronization stops at that point.

    Any idea where these file may be? I tried deleting the *.bin files in the SyncToy directory but that had no effect on the problem.

    SyncToy major problem – any way to fix?

    In contribute mode, laptop data is backed up to a hard drive by sync. Then, in the laptop, I delete a file to free space (this file already on the hard drive for archival), and a week later create a new file into the same folder with the same name but with unrelated content. Now, if I do a sync, then this new file overwrites the older one on the hard drive, even though the two are not each other’s updated version. This is data loss! Even happens when do the hash file content check.

    Any way around or fix?

    Jesse – I’ve just come across a lot of access denied errors when echoing to a remote file share.  I had permissions to read all of the files and it had me stumped.  Then I found that all of the problem files had the read only flag set – presumably when echoing a read only file the attributes are set before the file copy takes places, resulting in the denial of access.

    We were going to use SyncToy as a way of automating syncs between a development machine and live machine but the echo feature fails in its purpose to have an exact copy of the source on the destination (right hand folder). This is because for some reason it doesn’t delete folders – surely this is the contribute option but the ECHO option is selected. Is this a bug? When will it be fixed?

    I have two files on seperate networked computers where I need to keep the file on one computer updated daily with the changes that occur in the file on the other computer. (Simple so far!)

    The problem is these two files MUST have different filenames. The files are accessed by different applications (databases), and it is not possible to have the "receiving" file have it’s name changed.

    I would think this is possible, but I cannot find it in the SyncToy Help or anywhere online

    Please explain how this can be done.

    As an administrator I don’t get alerts when synctoy fails to backup users files from their PCs to the sever. How do I get the alert, any help?

    I used 2.0 under XP to synchronize between a usb connect harddisk and a network connect harddisk.

    When copying manually there is no problem, but when I synchronize big files, mostly jpg and mp3 files things went awfully wrong. On the copied picture you would see a 10-20% band of the picture and the rest would be gray. Same with copied mp3 files, after 10 seconds the song stops.

    In copying back and forth, this way my entire collection of 60GB of music was entirely ruined. Luckely I could recover from DVD back ups and the history of my account at the store.

    If the same had happened with my pictures I would have lost 12 years of memories. No more Synctoy for me

    Does anyone know where SyncToy saves settings of configuration? I would like to copy settings to another workstation.

    I got SyncToy to work with my FTP server. First i downloaded a program called ‘DirectNet Drive’ from Using this program i allocated my FTP server a virtual drive (Z:). Then I could use SyncToy using the Z: drive as my ‘right-hand’ drive.
