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.
gentoo is a file manager that uses the two-pane concept and is somewhat inspired by DOpus. It strives to be very configurable and lets you do all of the configuration from a GUI within the program itself. Filesystem access is done through the GIO virtual file system layer whenever possible. Using advanced file typing and styling systems, gentoo determines how to display files in its listings, and also how to act on them. The package includes a set of over 120 unique handcrafted icons for many different types of files.
X File Explorer (Xfe) is a filemanager for X. It is based on the popular, but discontinued, X Win Commander. Xfe is desktop independent and is written with the C++ Fox Toolkit. It looks similar to Windows Commander or MS-Explorer, and is very fast and simple. It features file associations, the ability to mount/umount devices, a directory tree for quickly changing directories, the ability to change file attributes, automatic registry saving, the ability to view/create/extract compressed archives, and much more.
JStart gives the ability to start Java class files (or applets) by double clicking on them from the desktop like any executable program. You only have to assign *.class files to this program. It loads a class file, investigates it according to the Java Sun class file specification, extracts the full class name (including packages), and invokes the main method of that class.
