The Q-Dir or Quad-Directory-Explorer is a file explorer and manager with an amazing Quadro-View technique. While using Q-Dir, you don't have to give up your usual work habits, drag'n drops, view types, and other standard functions of your current file manager. On the contrary, Q-Dir gives you extra useful functions. Save time by reducing mouse-clicks and hand movements.
Q-Dir's file management is based on MS Windows Explorer, but enhanced with the 4x plus Explorer Tab Views and more functionality! Q-Dir makes your files and folders easy to manage, either installed or as a portable Windows program.
More and more data makes for a larger file management challenge on your Windows OS, and such challenge is efficiently handled by Q-Dir. Q-Dir can be executed easily from the desktop, and can be carried on a small usb-stick or other memory device.
Q-Dir allows you to save folder combinations as a favourite to open any time. Up to 64 folder combinations can be saved in a favorite, since each of the four windows is equipped with tabs (ie 4 x 16 tabs 4 x Tree View plus 4 x Address Bar), different colors for different file types ...
