add entire folder to sourcesafe?

I have a folder with var开发者_如何学Cious files and subfolders that I'd like to add to my sourcesafe 8.0 database. In the SourceSafe explorer I can add files, but I don't see any options for adding an entire folder w/subfolders. Is it possible to do this?

It's been a while since I've used SourceSafe but I think you can just drag the folder into your project if I'm not mistaken.
