Double Commander is a dual-pane file manager. It is a free and open-source software licensed under the terms of the GNU General Public License. It is designed to be operated by a keyboard, a mouse, or by both at the same time.
It has support for tabs, bookmarks, customizable keyboard shortcuts, compressed files, checksums, and custom file list colors.
The default keyboard shortcuts and default functionality are inspired by the Total Commander for Microsoft Windows only. This makes it similar in operation to the original Norton Commander for DOS, which popularized the basic concept in the 1990s. It is a modern application, designed for use with the latest operating systems.
