Tray Nav is a utility that runs in the system tray (next to the clock). Tray Nav allows you to navigate any drives and folders on your computer via a menu that is displayed when the Tray Nav icon in the system tray is right clicked on. You can add any folders that you want to this menu. When you move your mouse over a folder in a menu, a submenu will pop up with a list of that folder's contents, and so on for all it's sub-folders. Tray Nav allows you to open any file or program.
