QDirStat is a graphical application to show where your disk space has gone and to help you to clean it up. From the author of the original KDirStat. This is a Qt-only port of the old Qt3/KDE3-based one, now based on the latest Qt 5. It does not need any KDE libs or infrastructure. It runs on every X11-based desktop on Linux, BSD and other Unix-like systems. QDirStat features both tree and treemap which makes easier to identify disk usage. With customizable disk cleanup actions predefined behaviour might be setup and then performed in easy way via context menu. QDirStat is also capable to show summary from aggregated data and visualize disk usage processed by various statistical methods.
