TreeTrim can be useful if you want to cleanup your projects.
It's a tool that strips out debug files and folders in your source code tree and also zips and emails amongst other things.
You can either run it from the command line or from Windows Explorer. The setup program intalls context menu commands when right-clicking on folders in Windows Explorer.

In one project I had it cleaned out 30 MB. I tested on a Visual Studio 2008 VB.NET project on Windows 7 and it worked great.
