.dsw files - to store on VSS or not?

[micc2]

I am working in a multi-user environment, and we have just started using VSS. I want to know which Visual Studio project files we need to store in SourceSafe.

In particular, do we need to store .dsw files?

We want to make it as easy as possible for programmers. To this end, we want to use the facility that automatically prompts the programmer to check out a file when they make a change. HOWEVER when I set this up, on opening the project in Visual Studio I get prompted to check out the .dsw and .dsp files. This is because they are read-only by default, and opening the project seems to "automatically" modify them on opening. So I want to avoid this.

If I don't need to store .dsw files, that takes one annoyance away.

I know I need the .dsp file, but is it possible to keep this as a read/write file by default to avoid the pop-up message on opening?

I've just realised, the reason the files are marked read-only is because I have ticked the box
"Use read-only flag for files that are not checked out".

Why does opening the project immediately atttempt to modify these files? Or does it just try to set them to r/w?
