Here is a useful Windows Vista tip. Select a file or folder, hold down Shift and right click. Some additional options shows up. Pin to Start Menu, Add to Quick Launch and Copy as Path. If it is a folder it also shows Open Command Window Here. The last one starts cmd.exe and navigates to that folder.
I like the idea of Copy as Path. It copies the complete path to the clipboard but I dislike that it adds quotation marks around the path.
"C:\Program Files\AutoCAD 2008\Sample\3D House.dwg"
I will post a solution for this later on that works in older versions of Windows as well.
