Just to expand on this - it will provide a mechanism to control who can update code in separate parts of the project, and to merge changes mae by two people to the same code (I'd recommend against this, strongly - it does a poor job.) It will not allow each person to work on the same copy of the project at one time - each person would check out a copy of the project separate and distinct from each other person's copy, amke their changers, and update the common VSS project at intervals. During compilation, VSS would ensure that any changes checked into VSS would be brought into the individual copy of the project.

It will not keep you from stomping all over some else's good work if two people are permitted to update the same project thing in parallel. It does provide version control, though, so that you can go back and back out changes or manually merge changes into parts of the project.

VSS is included with Visual Studio Enterprise - you'd have to purchase it separately if you do not have it now. It doesn't come automagically as a part of VFP by itelf.
