Tree Trim is a command line tool that trims your source code tree. It removes debug files, source control bindings, and temporary files.
It’s integrated with Windows Explorer: when you right click a folder you’re given the option to clean the folder.
Massive thanks to Scott Hanselman for blogging about it and for providing some great and detailed feedback.
