GNOME Commander is an open source application that provides users with a twin-panel file manager for Linux-based operating systems. It has been originally designed for the GNOME desktop environment.

The program can currently perform some of the most basic and common file operations, such as cut, copy, paste, move, delete, and rename. It can also copy only file/folder names, verify MD5 and SHA-1 hashes, send files via email using the default mail client.

The software can open the current folder in the default file manager application, open a terminal window in the current directory, open files with a specific application (e.g. text editor, web browser, etc.), connect to remote servers or a local Samba network, and compare directories.

Another interesting feature is the ability to quickly change the permissions of a file or folder, by accessing the Properties entry from the right-click context menu. It supports a horizontal layout, and a powerful search functionality.

Its user interface is very similar to the Midnight Commander, Norton Commander and Total Commander applications (some of the available only on the Microsoft Windows operating systems).

It offers a very efficient and fast way to manage your file and folders, provides support for the useful drag and drop functionality, GNOME mime types, FTP support using the GnomeVFS module, folder bookmarks, right-click context menus, and history.

The application is distributed as a universal source archive that can be used to configure, compile and install the program in any Linux distribution, as long as all requirements are met. The community provides binary packages for GNU/Linux (Gentoo, Sabayon, Debian, Ubuntu, Fedora, openSUSE, Frugalware, ALT Linux, Arch Linux) and BSD operating systems.

While it is called GNOME Commander, the application can be used under any open source desktop environment or window manager, such as Xfce, LXDE, Cinnamon, MATE, Enlightenment, Openbox, or Fluxbox.
