Krusader is a simple, easy, powerful, twin-panel (commander-style) file manager, similar to Midnight Commander (C) or Total Commander (C). It provides all the file management features you could possibly want. Plus: extensive archive handling, mounted filesystem support, FTP, advanced search module, viewer/editor, directory synchronisation, file content comparisons, powerful batch renaming and much more. It supports archive formats: ace, arj, bzip2, deb, iso, lha, rar, rpm, tar, zip and 7-zip. It handles KIOSlaves such as smb:// or fish://. Almost completely customizable, Krusader is very user friendly, fast and looks great on your desktop.

best gui linux file manager
My favourite file manager, archive manager and FTP client.
Krusader is good alternative to Midnight Commander.
Decent file manager if you dont like konqueror. Its really just a QT GUI based on Norton Commander and Midnight Commander. It does have some decent features for opening archives and handling certain file types.
