QDirStat review
A capable free analyzer for Linux and macOS users who need visual storage insight.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
QDirStat is a free, open-source graphical disk-usage analyzer for Linux and macOS. It is designed for users who need to locate large files, understand directory usage, inspect installed software, and clean up local storage. Its main workflow combines a hierarchical directory tree with a proportional treemap, helping users move from an overall view of disk consumption to individual files and folders. File-type statistics, file-age views, size histograms, and mounted-filesystem space information add further ways to investigate storage.
The pricing model is straightforward: the Free and open source plan is GPL v2 licensed, with no paid license required. The published plan emphasizes access to the application rather than tiered feature separation. QDirStat also fits well into supported Linux environments through integrations with dpkg, rpm, pacman, apt, and zypper. These integrations support installed-package and individual-file views, while cache-file reading and writing can preserve scan information for later review. Exported reports, multiple selection, and configurable cleanup actions broaden its usefulness beyond simple visualization.
QDirStat is strongest when storage analysis needs to remain visual, local, and focused on files, folders, applications, and mounted filesystems. Cleanup actions can include moving items to the trash or deleting them, so the tool suits users who want analysis and cleanup in one desktop application. Linux users get the broadest package-oriented context; macOS users get core disk-analysis capabilities, with binaries provided through a separate distributor repository referenced by the project. Users who require a native Windows application should choose an alternative, while QDirStat is a sensible fit for Linux and macOS users seeking a free open-source analyzer with multiple views.
