Xfce

Xfce (pronounced as four individual letters, ) is a free and open-source desktop environment for Linux and other Unix-like operating systems.

Thunar is a file manager for Linux and other Unix-like systems, initially written using the GTK+ 2 toolkit and later ported to the GTK+ 3 toolkit. It started to ship with Xfce in version 4.4 RC1 and later. Thunar is developed by Benedikt Meurer, and was originally intended to replace XFFM, Xfce's previous file manager. It was initially called Filer but was changed to Thunar due to a name clash.
