Collapse all files at once in Solution Explorer window in Visual Studio

Question

Is there a way to collapse all the files at once in the Solution Explorer window in Visual Studio?

Answer 1

I think this extension have requested functionality - PowerCommands for VS 2010. Also Productivity Power Tools contains solution navigator which also have this feature and much more usefull stuff for solution navigation and search.

Edited: there also a lot of examples of macro, doing this stuff.
