Double Commander is a cross platform dual-pane file manager inspired by the Windows-only Total Commander. In addition to allowing users to move files between the two directories displayed in its two panes, Double Commander can also compare the contents of those directories. It can be set either to highlight files that differ or those that are identical. For files that differ, Double Commander provides a built-in file comparison tool to determine what specifically is different. Users can bookmark specific locations for quick access in the future and can open numerous locations simultaneously in tabs. Archive files (for example, .zip or .tar) can be browsed as if they were directories without needing to unpack them. For quick changes to text file formats, Double Commander includes a built-in text editor. Double Commander also provides a full-text search feature to query within selected directories. Installers are provided on the Double Commander website for Windows, macOS, Linux, and FreeBSD systems.
