ShellGEM is a shell context menu enhancement that lets you access the complete directory tree of any drive or folder. Simply right-click on any folder or drive and select ShellGem. A directory tree is displayed, letting you open any file or folder, and perform file management tasks. A history folder lets you quickly open the last 10 folders accessed. You can unZIP, unRAR, unARJ and unJAR file archives using drag-and-drop. And if you often find yourself copying or moving files to the same directory, you can add the directory to a handy Favorites menu. ShellGem was formerly called ShrewdEX.
