We have an application and whenever we have a new release we do a "label" so we can have a snapshot of the code that belongs to that release.

Well, I need to get the files from a previous version so I went to the label that I needed, got those files and put them in a new directory. Now at this point I have all the files but not the project. I created a new project and attached all the files back to the project but... here's my problem, how do I know which files were "excluded" from the project?

Basically I would like to recreate the project as it was when the "label" was created. Going forward I'm gonna save the project file manually in some directory as well but this wasn't done before.

Thanks for your help.
