GNOME Commander is a fast and powerful graphical file manager. It has a "two-pane" interface in the tradition of Norton and Midnight Commander. It features drag'n'drop, GNOME MIME types, FTP, SFTP, and WebDAV using the GnomeVFS FTP module, SAMBA access, the ability to extend the context menu with entries to call external applications or scripts on the selected items, quick device access buttons with automatic mounting and unmounting, a fast file viewer for text and images, a history of recently accessed folders, and folder bookmarks.
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.
GNU Midnight Commander is a text-mode full-screen file manager. It uses a two panel interface and a subshell for command execution. It includes an internal editor with syntax highlighting and an internal viewer with support for binary files. Also included is Virtual Filesystem (VFS), that allows files on remote systems (e.g. FTP servers) and files inside archives to be manipulated like real files.
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.
