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, 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.

Pick WinDirStat if

- ·Two decades on Windows — the default 'how do I see what's eating my disk' answer for a generation of Windows users.
- ·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 as well as Windows — WinDirStat is Windows-only; one Diskaroo license covers both 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.

Bottom line
WinDirStat is free, open-source, still maintained, and has done one job well for two decades — if you're Windows-only, on a budget, and the classic UI doesn't bother you, just download WinDirStat. It works, it's free, the source is auditable, and millions of people have used it without complaint. We also will not claim Diskaroo is 'the fastest' — that's not our wedge and we won't fight WinDirStat or anyone else on scan speed. Diskaroo only makes sense if you also use a Mac (one license covers both desktops), you have real duplicate-file pain WinDirStat can't address, or you want one modern app with the same UI and in-app auto-update on both desktops. That's the buyer for Diskaroo. Everyone else: WinDirStat.
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 both Mac and Windows. 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 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 on both desktops 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 both Mac and Windows under one license, with built-in exact-duplicate detection.
