I was pleased this morning to read that SyncToy 2.1 made it to PC Magazine list of "Best Free Software for 2010". According to the article:
SyncToy is a tool that is based on the Sync Framework and is managed out of our group. With over 1.8 million downloads since the release of version 2.0, it continues to be a great example (and test) of the Sync Framework.
If you are interested in giving SyncToy 2.1 a try, it can be downloaded from here.
