What it is
QDirStat is a free graphical application for examining disk usage and helping clean it up. It shows directory and file sizes in a tree and a colored treemap, with additional views for file types, file-size histograms, file age, and free, used, and reserved space on mounted filesystems. Users can select multiple items and run configurable cleanup actions, including moving items to the trash or deleting them. On Linux distributions using dpkg, rpm, or pacman, the Packages view shows installed packages and their files; an Unpackaged Files view helps locate files in system directories that are not part of installed packages. QDirStat targets Linux, BSD, and Unix-like systems on X11-based desktops. macOS binaries and Homebrew distribution are linked through third parties, with macOS-specific support directed to the distributor. There is no native Windows version, though the project points to Docker as an option for non-Linux systems. A Perl script can gather directory data on a headless server for desktop viewing, but cleanup actions on cached data run on the desktop. Cache files may expose directory contents and should be protected accordingly. QDirStat is GPL V2 software.
For and against
For
- Shows disk usage in a tree and colored treemap.
- Includes file-type, age, and size views.
- Supports configurable cleanup actions.
- Can collect server directory data for desktop viewing.
- Free GPL V2 software.
Against
- There is no native Windows version.
- macOS support is directed to third-party distributors.
- Cached data cleanup runs on the desktop.
- Cache files may expose directory contents.
The verdict
QDirStat provides multiple ways to inspect disk usage and lets users apply cleanup actions to selected items. Check platform support and protect cache files when using its server workflow.
Who it suits
QDirStat suits users who want a graphical breakdown of disk usage and configurable cleanup actions on Linux, BSD, or Unix-like systems. Its cache workflow can also help people inspect remote servers or large directories that change infrequently.
