muCommander is a free, open-source file manager with dual-pane interface that runs on Windows, macOS, and Linux. Written in Java, muCommander provides consistent file management experience across platforms with features for both local and network file operations.
The dual-pane layout displays two directories simultaneously with configurable views including details, icons, and thumbnails. Tabs within each pane enable switching between multiple locations quickly. Quick search filters visible files by typing name characters.
Local file operations include copy, move, delete, rename, and permission changes. Archive browsing treats ZIP, TAR, GZIP, BZIP2, 7z, RAR, and other formats as virtual directories. Pack and unpack operations create and extract archives. Archive creation supports multiple formats with compression options.
Network protocol support includes FTP, SFTP, SMB/Windows shares, NFS, HTTP, HDFS, and Amazon S3. Bookmarks store connection settings for quick access to network locations. Credentials manager handles authentication securely.
The batch rename function changes multiple file names using patterns, search and replace, counters, and other transformations. Calculate folder sizes shows actual disk usage. Compare directories highlights differences between folders.
Customizable keyboard shortcuts match other file manager conventions or create personal mappings. Themes change visual appearance. Command bar buttons launch custom commands. Configuration files enable portable setup across installations.
