Filelight

Filelight is a powerful software tool that is designed to help users understand exactly where their disk space is being used. This handy program uses a graphical representation of your filesystem that is shown as a set of concentric segmented rings. By creating a complex, yet data-rich view of your files and directories, Filelight provides a clear overview of your computer's storage system.

One of the standout features of Filelight is its ability to provide a visual representation of disk usage. For example, when looking at KDE's disk usage, you can see that the full circle represents 143MB, and that there are 143MB of files contained recursively in the directory. Filelight even provides detailed information about individual files and directories, including their size and location.

Another useful feature of Filelight is its ability to represent directories as child-segments that contain files. This makes it easy to see exactly which files are taking up the most space in any given directory. By hovering over any segment, you can quickly see details about the file it represents.

Overall, Filelight is an essential tool for anyone who needs to manage disk space. With its intuitive interface and ability to quickly identify storage usage, this program stands out above the rest. Filelight is released under the GNU General Public License, making it a valuable resource for anyone who values open-source software.
