Diskaroo vs WinDirStat — honest comparison
Looking for a WinDirStat alternative? Here's an honest Diskaroo vs WinDirStat comparison. WinDirStat is the free, open-source Windows treemap classic — two decades of helping people clean up disks, Windows-only, still maintained, and it costs nothing. Diskaroo vs WinDirStat only makes sense if you also use a Mac or a Linux machine, want exact byte-identical duplicate detection, or want a modern cross-platform UI. WinDirStat is free and Diskaroo isn't, and we'll say that plainly. We will not claim Diskaroo is "the fastest" — that is not our wedge.

- ·Tiny footprint — installs in seconds and runs on essentially anything Windows ever shipped, including older machines where modern apps feel heavy.
- ·Source code is auditable — for regulated environments that can't run un-inspectable closed-source utilities, that matters.
- ·No commercial-vs-personal license question — WinDirStat is free for any use.
Pick Diskaroo if
- +Runs on Mac and Linux as well as Windows — WinDirStat is Windows-only; one Diskaroo license covers all three desktops.
- +Exact, byte-identical duplicate detection via a three-pass match (size, then a 64 KB partial hash, then a full hash), included in the one $19.99 purchase — WinDirStat ships no duplicate finder.
- +In-app auto-update and a cross-platform codebase — WinDirStat ships the same app on Windows only and updates by manual download.
- +Modern review-before-trash collector tray — stage a whole batch across folders, confirm once. WinDirStat works file-by-file in classic Explorer style.
- +Native treemap with smooth drill-in and breadcrumbs — WinDirStat's treemap is functional but visually dense and doesn't drill in cleanly.

FAQ
Is WinDirStat really free?+
Yes. WinDirStat is GPLv2 open source — no paid tier, no subscription, no telemetry upsell. Diskaroo is a one-time $19.99 (no subscription) covering Mac, Windows, and Linux. If price is the deciding factor, WinDirStat wins, full stop.
Is Diskaroo faster than WinDirStat?+
We don't make a speed claim. Diskaroo's advantages are cross-platform coverage (Mac + Windows + Linux on one license), built-in exact-duplicate detection, a modern UI, and in-app auto-update — not raw scan speed.
Does WinDirStat find duplicate files?+
No. WinDirStat is a pure visualizer — it shows what's taking space but doesn't compare files. Diskaroo runs a three-pass byte-exact match (size, then 64 KB partial hash, then full hash), included in the one $19.99 purchase. It finds exact copies only — not similar or fuzzy matches — and skips files under 1 KB.
Can I run WinDirStat on a Mac?+
No. WinDirStat is Windows-only. Mac users typically reach for DaisyDisk, GrandPerspective, or Diskaroo. If you want one tool across Mac, Windows, and Linux under one license, Diskaroo is the answer; if you don't need the Mac side, WinDirStat is fine.
Is WinDirStat still maintained?+
Yes. WinDirStat at windirstat.net is open-source and still receiving updates. It is Windows-only with a classic Windows UI. Diskaroo's difference isn't 'more maintained' — it's running the same modern app on Mac, Windows, and Linux under one license, with built-in exact-duplicate detection.
