X File Explorer (Xfe) is a graphical file manager for the X Window System for Linux and Unix-like operating systems. It an MS-Explorer or Commander like file manager for X. It is based on the popular, but discontinued, X Win Commander, originally developed by Maxim Baranov.
From the blog:
Nearly all Linux distros come with a graphical file manager tied to a particular desktop environment. KDE comes with Dolphin file manager, Gnome with Files, MATE with Caja, Cinnamon with Nemo, Xfce with Thunar, LXDE with PCManFM.
You’re not, of course, stuck with the file manager that comes with your DE, if you prefer another one. For example, until recently I ran my Debian Xfce system with PCManFM rather than Thunar, while my wife stuck with Thunar even when MATE was her desktop environment.
I now use a graphical file manager that’s completely independent: not tied to any particular distro or DE. And I really like it.
