Xfe file manager: an independent marvel
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. [...] I now use a graphical file manager that's completely independent: not tied to any particular distro or DE. And I really like it.
