In your CONFIG.FPW you would add a line like this:

RESOURCE=C:\MYPATH\FOXUSER.DBF

and you'd start your VFP app with:

yourVFP.EXE -cC:\MYPATH\CONFIG.FPW

If the locations are on a network drive, be sure that each user has their own folder, or uses a unique name for the CONFIG.FPW and the FOXUSER.DBF

RESOURCE=X:\USER1\FOXUSER.DBF
or
RESOURCE=X:\MYPATH\USER1.DBF

There are many permutations you can come up with that should work.
