TFS terminology

I would call thingy 'C' a folder, but how should I refer to thingies 'A' and 'B'?

The screenshot beflow is from the Visual Studio Source Control Explorer IDE.

I always refer to such things by their name (as in "Go to TFS, Customer Tools, Database").

I suppose TFS doesn't really need a name (it's the TFS root - seems self-explanatory to me).
Customer Tools looks like what other SCM systems call a "project", so unless a TFS guru says different that's what I'd call it.
