You can use the Double Commander file manager for regular file management functions and a lot more.
The default file manager in your distro is good enough for most tasks, but third-party options can do a lot more. The cross-platform Double Commander is one such option that’s inspired by the popular Windows-only Total Commander file manager.
Double Commander is available as a portable release for both GTK and Qt-based desktops. You can also grab it as an AppImage. Once downloaded, make the AppImage executable either with the chmod +x command, or through your default file manager.
Double Commander is an orthodox file manager with a dual-pane interface. You can operate it via the mouse or keyboard. The default keybindings are the same as in Total Commander, but can be remapped.
The app works just like any other file manager and can perform all the usual tasks you expect from such a tool. Most of the common operations are rolled up in the right-click context menu, while the Files menu houses some interesting ones. For instance, you can change the attributes of a file, get a count of the files and subfolders inside a folder, and their total size, split and combine files, calculate and verify file checksums, and a lot more.
