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.
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.
