In general a file manager is a program that gives some kind of interface to the file system and that show in a graphical or textual way the files and directory, usually a file manager allow to do some standard operations such as delete, rename copy/paste and other typical operations that you can do on files.
Twin-panel file managers have obligatory connected panels where action in one panel results in a reaction in the second. So for example you could move a file from the first to the second panel, or copy it. In this roundup I‘ll show you some of the most used Twin-panel file manager available on Linux, sometimes they are also called Orthodox file managers or command-based file managers and in general they have three windows (two panels and one command line window).
Note: Konqueror supports multiple panels divided horizontally, vertically or both, but these panels do not act as twin panels by default (the user has to mark the panels he wants to act as twin-panels), so I’ll not put it in this article.
One of my favorite Distribution, but also the name of a twin-panel file manager.
Latest: 0.19.13 Released: 2012-03-18
Gentoo, is a GTK+ file manager. The current release series of gentoo is called 0.19.x. It is based on the 2.x series of the GTK+ toolkit.
Gentoo provides a two directory pane listing with sticky toggling of selections, A pile of operations you can do in or across directories, highly customizable file recognition, easy extension and generally gets out of the way of doing real work.
Some of Gentoo’s main features include:
- Reasonably small and fast (written in C).
- Support for most typical file operations (copy, move, rename, makedir etc.).
- Uses GIO, which means file system access is virtualized.
- Direct graphical configuration of most main features.
- A powerful file recognition system that allows you to configure how files of different types are listed (what colors and icons), and what happens when you double click them (start image viewers, music players, etc.).
- Includes more than 120 original pixmap icons.
This is another twin-panel manager done with GTK+ 2, clean and simple.
The latest source-code release is: emelfm2-0.8.1.tar.bz2 (1073 kb) – Released 2012-04-20
The main window is divided into three parts. Two of those (side-by-side or top-to-bottom) show the contents of selected filesystem directories. The third pane, at the bottom of the window, shows the output of commands executed within the program. Those panes can be resized, and any one or two of them can be hidden and unhidden, on request. A built-in command-line, toolbar buttons or assigned keys can be used to initiate commands.
Some feature of this software are:
- Bookmarks and history lists
- An embedded Trashcan that saves all your deleted files
- Drag and Drop between the 2 panels
- Filters to display files/directory that matches a particular pattern
- An output box on the bottom to show the result of commands
NOTE: There is also emelFM a file manager that implements the two-pane design in a simple GTK+ interface.
As you can expect from the starting K Krusader is a file manager born for the KDE Desktop Environment.
Last Stable is the version 2.0.0 – Release date: 2009-Apr-11, a beta release is updated regularly.
Krusader has a lot of options compared to many of the other softwares in this category, it can connect to a remote server via SFTP or FTP and compare local and remote files, or do an extensive search for files in the filesystem, Krusader supports archive formats: ace, arj, bzip2, deb, gzip, ISO, lha, rar, RPM, tar, zip and 7-zip and handles other KIO Slaves such as smb:// or fish://.
Krusader also includes a built-in Mount-Manager MountMan, which enables you to mount or unmount file systems of all types with a click of a mouse. The user is able to obtain usage and other property information easily, in a consistent and understandable format in seconds.
A Bookmark-Manager for local files/remote URLs and an Advanced Search module is also included to speed the locating of needed files. Krusader also allows the user to configure Toolbars in order to provide a wide variety of additional functionality, such as File Comparison (several user selectable methods available), Multiple File Rename, and standard Terminal windows.

GNU Midnight Commander (also known as MC) is a free cross-platform orthodox file manager and a clone of Norton Commander. It was started by Miguel de Icaza in 1994.
This is my favorite software in this category, it works perfectly in a terminal and so is useful also on server without any Desktop Environment.
The main interface consists of two panels which display the file system. File selection is done using arrow keys, the insert key is used to select files and the Function Keys perform operations such as renaming, editing and copying files. Later versions of the Midnight Commander additionally have mouse support. Such versions are aware of GPM and X terminal emulators (such as GNOME Terminal or xterm) which support mouse reporting.
- Support for all basic file operations including move, copy, rename, delete, chown, link, view, and edit
- a built in Virtual File System that allows browsing of archives such as tar, compressed tar, RPM, deb, zip, cpio, lha, rar, and zoo files as well as remote files via FTP or the Midnight Commander’s own mcfs protocol
- Mouse support in xterms under X or at the Linux console via the gpm mouse server
- Built in text and hex viewer/editor as well as support for external viewer and editors
- Subshell support for the bash, tcsh, and zsh shells
- Built in Find File capacity
- Background copy or move operations
- Online help system
Vifm is a ncurses based file manager with vi like keybindings. If you use vi, vifm gives you complete keyboard control over your files without having to learn a new set of commands.
Last Version vifm v0.7.2 released on February 19, 2012
As noted the main feature of this file manage is his key binding based on Vi commands so for example you can use these key bindings:
yy – Yank a file (or “copy” it).
p – Put a file (or “paste” it).
dd – Delete a file.
Enter – View a file.
t – tag the current file (you can do an action on multiple tagged files)
/ – Search for a file (the / character is followed by your search string).
gg – move to the top of the file list.
G – move to the bottom of the file list.
The Space Bar or Tab Key toggles between the two file lists.
So, you can move over a file “Yank” it with “yy” then use the space key or tab to move on the second panel, move around the filesystem and once you reach the destination paste it with the “p” key, easy if you are Vi addicted .
So you like vi syntax but for some reason you don’t like vifm ?
No problem there is an alternative Twin-Panel file manage that use vi syntax: Ranger
Ranger provides a minimalistic and nice curses interface with a view on the directory hierarchy. The secondary task of ranger is to psychically guess which program you want to use for opening particular files, Ranger is developed in Python 2.6, Last version is 1.5.3 released on 2012/03/05.
Optionally you can install these programs to have a better preview/information on your files:
- img2txt (from caca-utils) for previewing images
- Highlight for syntax highlighting of code
- Atool for previews of archives
- lynx, w3m or elinks for previews of html pages
- Pdftotext for pdf previews
- transmission-show for viewing bit-torrent information
- mediainfo for viewing information about media files
- UTF-8 Support
- Preview of the selected file/directory
- Common file operations (create/chmod/copy/delete/…)
- VIM-like console and hotkeys
- Automatically determine file types and run them with correct programs
- Change the directory of your shell after exiting ranger
- Tabs, Bookmarks, Mouse support
This is the last software in this category it’s probably the most recent, but show good potentials.
Sunflower is a small and highly customizable twin-panel file manager for Linux with support for plugins. It is intended to be an easy-to-use and powerful file manager that seamlessly integrates into the GNOME desktop environment, currently this project is still in its early alpha stage.
