What is thunar?

Thunar

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