Right now I'm working with an ASP.NET website that automatically generates images and stores them in a temporary folder. When working on my local system these go going into a temporary folder that gets picked up by Visual Source Safe which then wants to check them in. As such, I am wondering if there is a way to just exclude that particular folder from source control?
I've done a bit of reading and found that there are ways to do this for individual files, but I haven't found anything yet about an entire folder.
I think you've found one of the main reasons MS went back to projects in VS2008 and in MVC.
It's been a long time since I've used VSS (mainly because it's really out of date now), but most source providers let you exclude files and folders as a setting of the provider, rather than the project under control.
If you can switch to a Web Project rather than a WebSite then do so, otherwise I'd look at updating your source control provider, as this sort of exclusion is easy with Vault, CSV, SVN, Git, VSTS and so on (to name but a few).
