File Commander is a text mode file manager and shell in the style of Norton Commander. It allows you to locate, copy, move, delete, view, edit, and execute your files. Its main display provides dual directory view panels which may be used to view a file list, a directory tree, or volume statistics. A command line is also provided and operates in conjuction with the directory panels to make it much more powerful than a regular CLI. Other features include built in support for archives, Unicode file name support, a built in viewer and editor with syntax highlighting, and Unicode text file support.
Every five minutes, Tumblefile copies all files on your Desktop to a folder such as ~/Documents/2009-07-July/25-Saturday, prepending a timestamp (like 20090727.1645) to the filename. Meanwhile, its little window sits in the system tray. It is a way to automatically keep your Desktop cleared and files organized.
Ridual is a dual-pane file manager for GNOME. It features tight integration with GNOME (providing GVFS mount support, bookmarks and user directories, a removable drives list, file icons, and application associations), keyboard-oriented control (with adjustable shortcuts for everything, single-window dialogs, and messages), and advanced tasks and queues management.
FileRunner is a two-pane file manager for Unix. It is simple and efficient and has a built-in FTP/SFTP/adb client. It does a reasonable (and improving) job on Windows systems. It features a simple and powerful interface, history and Hotlist (bookmarks), a recursive directory menu of the entire filesystem tree, browsing FTP, sFTP, and adb directories as easily as normal directories, asynchronous file transfers, cached directory listings, asynchronous file operations, built-in command shell windows synchronized with file panels, extensibility by adding your own command buttons, and user-defined file pattern/actions.
