Krusader is an advanced twin-panel (commander-style) file-manager for KDE 3.x, but with many extras. It provides all the file-management features you could possibly want. It also features extensive archive handling, mounted filesystem support, FTP, an advanced search module, a text viewer/editor, directory synchronization, support for file content comparisons, powerful batch renaming, and much more. It supports the following archive formats: tar, zip, bzip2, gzip, rar, ace, arj, and rpm. It can also handle other KIOSlaves such as smb:// or fish://.
Dealing with the UNIX command line, especially in order to manipulate the file system, is one of the biggest hurdles to widespread use of Unix and Linux. System G was written to provide a simple way to access to the file system in the form of a graphical hierarchy of files and folders.
Worker is a file manager for the X Window System with the classical two panel interface. It features a fully graphical configuration, while still allowing manual editing of the configuration file without the need to restart Worker. Any external program can be integrated easily into the GUI using buttons, hotkeys, and file type actions. Worker uses file recognition by file content or by filename extension (or both). Different actions with completely configurable commands can be assigned to each file type.
xdiskusage is a user-friendly program to show you what is using up all your disk space. It is based on the design of the "xdu" program written by Phillip C. Dykstra. Changes have been made so it runs "du" for you, and can display the free space left on the disk, and produce a PostScript version of the display.
ThreeDFM is a 3D file manager that uses OpenGL. Currently, only file system browsing is implemented. The main reason for this project is that using a 2D file manager is slow. More information about files can be conveyed in 3 dimensions. Not only will you be able to see the file's properties, but you will quickly be able to see a particular file's relationship to the others in the surrounding directories. A simple example of this is the file's size, as this can be shown by the size or colour of its representation. It will also be possible to view the contents of multiple directories simultaneously as they stretch off into the distance.
