Krusader is an advanced twin-panel (commander-style) file-manager
for KDE 3.x (similar to Midnight or Total Commander) but with many
extras. 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 the following archive formats:
tar, zip, bzip2, gzip, rar, ace, arj and rpm and can handle
other KIOSlaves such as smb:// or fish:// It is (almost) completely
customizable, very user friendly, fast and looks great on your desktop!
