If, for example, your application is mapped to a logical drive when running against a server, you could copy all the files to your local machine and just the logical drive to your local machine instead... This way, you don't corrupt the server drive data...

I do this regularly by using an old DOS command that still works... SUBST (substitute a local drive letter for an alternate logical drive)

ex:
C:\WINDOWS\system32\subst.exe m: c:\MyTestEnvironment\Client1


This will create a logical "M:" drive pointing to c:\MyTestEnvironment\Client1 as the root level...
