KDirStat is a graphical disk usage utility, very much like the Unix "du" command. In addition to that, it comes with some cleanup facilities to reclaim disk space. While KDirStat is a KDE program, it runs fine on every X11 desktop, i.e., it runs on Linux, BSD, and lots of other Unix-type systems (Solaris, HP-UX, AIX, ...).
