Filelight is a graphical disk usage analyzer part of the KDE Gear.
Instead of showing a tree view of the files within a partition or directory, or even a columns-represent-directories view like xdiskusage, it shows a series of concentric pie charts representing the various directories within the requested partition or directory and the amount of space they use. This method is known as a multilevel pie chart, sunburst chart or ring chart. Users may also on the pie-chart segment representing a particular directory and repeat the analysis for that directory, right click that segment to open a file manager or terminal emulator in that location, or copy to clipboard or delete the directory, and right click the segment representing a file to open it, copy it to the clipboard, or delete it.
