How to reference a Folder as a Drive Letter
Microsoft SQL Server Escalation Services
While assisting a customer with a SQL 2000 Replication configuration on Windows 2003 we need to reference the \ReplData folder as a Driver Letter. With help of Rick Rieser and Ryan Mangipano from Microsoft Windows Support team we had a simple elegant solution; Windows subst command.
— Example below creates an alias V: drive to the c:\temp\repldata folder.
C:\Temp>subst V: c:\temp\Repldata
— We can now reference the folder like a drive letter
Volume in drive V has no label.
Volume Serial Number is 206B-3D35
Directory of V:\
06/26/2011 09:08 PM <DIR> .
06/26/2011 09:08 PM <DIR> ..
2 Dir(s) 43,656,921,088 bytes free
— When done we can remove alias drive letter reference
— Contents of the folder are not deleted, just Windows reference to the V: drive
C:\Temp>subst V: /D
— As expected, folder reference is removed and can no longer be displayed
The system cannot find the path specified.
