Krusader is a simple, easy, powerful, twin-panel (commander-style) file manager for KDE and other desktops, 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, viewer/editor, directory synchronisation, file content comparisons, powerful batch renaming and much 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.
In comparison to GNOME Commander, I think Krusader definitely wins by a lot of points. I like GNOME Commander’s multi-renaming tool a little bit better than Krusader/KRename because GNOME Commander’s by default supports more built-in metadata standards like EXIF and ID3.
The features in Krusader are very much like Total Commander (on Windows) and not only that, they look and laid out in a very similar way too. I’m not really sure if this type of UI is the best UI in the world (that virtually almost everybody is cloning), but it seems to be quite efficient in screenspace usage. And when speaking of features, well, Krusader is probably more powerful than you can ask. 🙂
