What QDirStat is
QDirStat is a free graphical application for examining disk usage and cleaning up files. It displays directory and file sizes in a tree and colored treemap, alongside views for file types, size histograms, file age, and free, used, and reserved space on mounted filesystems. Users can select multiple items and apply configurable cleanup actions, including moving items to the trash or deleting them. On Linux distributions using dpkg, rpm, or pacman, its Packages view shows installed packages and their files; an Unpackaged Files view helps identify files in system directories that do not belong to installed packages. The project 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 for non-Linux systems. A Perl script can collect directory data on a headless server for desktop viewing; 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.
Good
- Shows usage in both tree and treemap views.
- Includes file-type, size, and age analysis.
- Supports configurable cleanup actions on multiple items.
- Can collect headless server data for desktop viewing.
- Free under GPL V2.
Watch out
- There is no native Windows version.
- macOS support is directed to third-party distributors.
- Cached server cleanup runs on the desktop machine.
- Cache files may expose directory contents.
Who it suits
QDirStat suits people who want a visual breakdown of disk usage and configurable cleanup actions on Linux, BSD, or Unix-like desktops. Its cache workflow also serves remote servers and large directories that change infrequently.
Verdict
QDirStat combines visual disk analysis with cleanup tools and package-aware views on supported systems. Check platform support and protect server cache files, especially when using its remote-data workflow.
