Disk space analyzer

QDirStat is a graphical application to show where your disk space has gone and to help you to clean it up.

This is a Qt-only port of the old Qt3/KDE3-based KDirStat, now based on the latest Qt 5. It does not need any KDE libs or infrastructure. It runs on every X11-based desktop on GNU/Linux, BSD and other Unix-like systems.

QDirStat has a number of new features compared to KDirStat. To name a few:


- Multi-selection in both the tree and the treemap.

- Unlimited number of user-defined cleanup actions.

- Properly show errors of cleanup actions (and their output, if desired).

- Configurable file categories (MIME types), treemap colors, exclude rules, tree columns.

Package manager support

- Show what software package a system file belongs to.

- Packages view showing disk usage of installed software packages and their individual files.

- Unpackaged files view showing what files in system directories do not belong to any installed software package.

New views

- Disk usage per file type (by filename extension).

- File size histogram view.

- File age view.

- Free, used and reserved disk size for each mounted filesystem (like df)
