Coalde UpFolder is a FREE tool for Windows Vista and 7 that lets you middle-click the mouse to go up one folder level when browsing folders. It emulates the "up arrow" button's functionality found in Windows XP, but without actually modifying your system to put a button there (we respect your PC and leave it alone).There are also two bonus features for your convenience: if you hold down Ctrl while middle-clicking, then the folder path will be copied to the clipboard; or hold down Alt while middle-clicking to have a DOS prompt opened at the folder. Both of these are very useful for advanced users.
