Krusader is an advanced twin panel (commander style) file manager for KDE and other desktops in the *nix world, similar to Midnight or Total Commander. It provides all the file management features you could possibly want.
It supports a wide variety of archive formats and can handle other KIO slaves such as smb or fish. It is (almost) completely customizable, very user friendly, fast and looks great on your desktop! You should give it a try.
