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.
Vimv is a utility to help rename various files at once using a text editor. It opens the list of files in a directory inside a text editor (vi by default). Then, any changes made in the editor will be reflected in the filesystem (the files in the directory will be renamed to the names saved in the editor).
Ranger is a file manager with an ncurses interface. It is designed to give you a broader overview of the file system by displaying previews and backviews, dividing the screen into several columns. The keybindings are similar to those of other console programs like vim, mutt, or ncmpcpp, so the usage will be intuitive and efficient.
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.
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.
4Pane is a four pane detailed-list file manager for Linux. It is designed to be fully-featured without bloat, and aims for speed rather than visual effects. In addition to standard file manager things, it offers multiple undo and redo of most operations (including deletions), archive management including 'virtual browsing' inside archives, multiple renaming/duplication of files, a terminal emulator, and user-defined tools.
