kdirstat: KDirStat (A graphical disk usage utility)
kdirstat: 
kdirstat: Very much like the  Unix "du" command. It  displays a  directory tree
kdirstat: both in  classical  tree format (like Konqueror, but with accumulated
kdirstat: tree sizes, shown as MB / GB and as percentage bars) and in "treemap"
kdirstat: format  like  SequoiaView.  In  addition  to  that, KDirStat provides
kdirstat: cleanup  facilities  to  reclaim  disk  space  -  both predefined and
kdirstat: customizable.
