Guix

Krusader is a simple, easy, yet powerful, twin-panel (commander-style) file manager, similar to Midnight Commander or Total Commander

It provides all the file management features you could possibly want. Plus: extensive archive handling, mounted filesystem support, FTP, advanced search module, an internal viewer/editor, directory synchronisation, file content comparisons, powerful batch renaming and much much more. It supports a wide variety of archive formats and can handle other KIO slaves such as smb or fish.

Almost completely customizable, Krusader is very user friendly, fast and looks great on your desktop.
