Filelight allows you to quickly understand exactly where your diskspace is being used by graphically representing your file system as a set of concentric segmented-rings. You can use it to locate hotspots of disk usage and then manipulate those areas using a file manager.
The latest stable release is version 1.12, included in KDE SC 4.9. Filelight is a free and open source software, available for Linux and similar operating systems under the GNU General Public License (GPL), Version 2.
