When it comes to file managers, there’s such a rich range to choose from on Linux, one could get confused and just go with the default one provided by their distribution or desktop environment (like most do, actually). However, Dolphin or Nautilus are not the only kids on the block here. After reviewing Sunflower, it’s time to have a look at yet another twin-panel file browser, namely, Double Commander, which is a powerful twin-panel file manager which provides interfaces for both GTK and Qt, so it blends well in both GNOME and KDE, depending on which version you install, and comes with a bunch of configuration options and usability features.
