TreeSize report card
Good · out of 4.0 · graded Nov 12, 2026
Best for finding what fills a Windows drive
TreeSize charts what is using disk space on Windows, with a free edition for home use. Duplicate search and usage comparison need a paid edition, the prices are in euros, and it runs only on Windows.
Who TreeSize is for
- Fits if you need to find what fills a Windows drive
- Works for IT staff who want scheduled storage reports
Who TreeSize is not for
- Skip it if you use Mac or Linux, as it is Windows only
- Not for you if you want free at work, as the free edition is for private use only
- Tight if you need duplicate search, since that needs Personal at 20.40 EUR a year
- Watch out: prices are in euros and may differ by region

Keep TreeSize, or make your own?
Keep it
The plain part of TreeSize you could make: reports. What surrounds it you could not. The 4 things listed below take a company, not a weekend.
What you could make
- Reports: an app builder makes this well.
What you could not
- Deleting system files without breaking anything.
- A file manager working directly on your disk.
- A real app for Windows. Something home-made would be a web page.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. TreeSize’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
