Kdirstat - a graphical disk usage display for TDE.
KDirStat (TDE Directory Statistics) is a small utility program that sums
up disk usage for directory trees, very much like the Unix 'du' command.
It displays the disk space used up by a directory tree, both numerically
and graphically. It is network transparent (i.e you can use it to sum up
FTP servers) It comes with predefined and user configurable cleanup
actions. You can directly open a directory branch in Konqueror or the
shell of your choice then compress it to a .tar.bz2 archive or define
your own cleanup actions.
