We had the same questions and this helped a lot

>Hi,
>
>I am having trouble understanding how VSS source control works within a VFP6 project.
>
>As I understand it, the VFP .pjx/t files sit on the local hard disk of each developers machine
>
>The .PJM file sits in VSS with a local copy on each machine
>
>When a developer has made changes, he hits "update project list", this copies all local changes back into the central PJM and gets other developers' changes
>
>Problem is that the PJM file is then checked out on the VSS database and other developers cannot run "update project list"
>
>Should I have multiple PJM's on VSS (1 for each developer)? or should I enable multiple checkouts? (Which I really don't want to do!)
>
>TIA
