QDirStat as a Linux alternative to TreeSize Free
Updated
Our verdict
QDirStat is a solid Linux alternative to TreeSize Free for users who need a graphical overview of disk usage and occasional cleanup. It offers a tree view and a treemap, lets you delete files to trash, and can export data, which covers most everyday tasks. Power users who rely on extensive scripting or need deep command‑line integration may still prefer a CLI‑only tool, but for typical desktop users the feature set is more than adequate.

What works the same
- Tree view of directories with size information
- Ability to sort or filter by size
- Export of statistics to text/CSV
- Graphical interface for quick inspection
What is different
- QDirStat includes a treemap visualization, TreeSize Free does not
- QDirStat can delete files to trash directly from the UI, TreeSize Free only marks for deletion
- TreeSize Free offers a command‑line mode for scripting; QDirStat lacks a native CLI interface
- Export formats may differ; TreeSize Free can copy results to clipboard more directly
Opening your TreeSize Free files
QDirStat does not understand TreeSize Free's proprietary report files. You can manually copy or re‑export data from TreeSize Free as plain text or CSV and then import that into QDirStat if needed, but there is no automated conversion. If you only need the exported CSV, QDirStat can read similar CSV structures, so re‑creating the report is straightforward.
Switching from TreeSize Free to QDirStat, step by step
- Install QDirStat from your distribution’s repository or via Flathub
- Run QDirStat and let it scan the desired partitions
- Compare the tree view with your TreeSize Free output to verify sizes
- If you need exported data, use QDirStat’s Export to CSV feature
- Delete or move unwanted files using the built‑in trash function
- Optionally, create a script that calls QDirStat’s command‑line options for automated scans
