What it is, who it suits, its grades and the ten things to know first

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | Personal is 20.40 EUR a year, inside the category's cheaper quarter. Professional starts at 41.00 EUR. |
| Free plan and trial | B | TreeSize Free covers a treemap and PDF reports for private, non-commercial use. Home users could live on it; business use cannot. |
| Features | B | Charts, large-file and duplicate finding, cloud and network scans, scheduled reports and exports. Duplicates and comparison are paid. |
| Ease of use | B | No rating on record. You pick a drive and it scans, with nothing to set up. |
| Platforms and integrations | D | Windows desktop editions only. It scans cloud targets like S3 and SharePoint, but runs nowhere but Windows. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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 it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
