Thunar is a new modern file manager for the Xfce Desktop Environment. It has been designed from the ground up to be fast and easy-to-use. Its user interface is clean and intuitive, and does not include any confusing or useless options. Thunar is fast and responsive with a good start up time and directory load time.
Thunar implements the various FreeDesktop.org standards to integrate nicely into todays UNIX/Linux desktop world. That means that you don’t need to setup your system in a special way or spend hours configuring the file manager, instead, it will just work if your system complies with the FreeDesktop.org standards.
