Thunar is a lightweight file manager included in the Xfce desktop environment. It has a simpler interface compared to Nautilus, the default file manager which ships with GNOME. So, what are the features which come with Thunar, and what makes it a viable alternative to Nautilus? First of all, it is lighter on resources and offers less functions than its GNOME counterpart, making it a very good choice for users who don't need advanced features, and prefer speed over those. Being the default file manager in Xfce, Thunar also comes included in lighter distributions like Xubuntu, which is the Xfce-based distribution of Ubuntu. The version of Thunar I used for this review is 1.0.0, tested in GNOME 2.26.1, as they come with Ubuntu 9.04 Jaunty Jackalope.
