Diskaroo is a consumer-facing disk visualizer that also runs on Mac and Linux. Diskaroo vs TreeSize is really 'consumer cross-platform tool vs Windows IT-admin suite' — different buyers, different jobs.

Pick TreeSize if
- ·Network share scanning at scale. TreeSize is built for IT admins who scan file servers, not just local drives — Diskaroo focuses on local volumes.
- ·NTFS permission reports and file ownership reporting. For Windows admins who need to know who owns what across a server, TreeSize is the category default.
- ·Scheduled scans on the Professional tier — Diskaroo doesn't do scheduled scans at all; every scan is run manually.
- ·Command-line parameters and task scheduler integration on Pro. Scriptable, automatable, and built to fit into existing IT workflows.
- ·Custom export formats — Excel, HTML, PDF — for handing reports to stakeholders. Diskaroo doesn't have report exports.
Pick Diskaroo if
- +One purchase covers Mac, Windows, and Linux. TreeSize is Windows-only and pricing scales per-user-per-month, so a small team with Mac or Linux users needs a different tool for those machines.
- +Consumer-friendly pricing. $19.99 lifetime once, all three platforms. TreeSize Professional's annual subscription crosses Diskaroo's lifetime price in the first year for a single seat.
- +Byte-exact duplicate detection with a deterministic three-pass strategy (size group, 64 KB partial hash, full-file hash). TreeSize has duplicate detection on the Personal tier and up; Diskaroo's is byte-exact and included in the one $19.99 purchase.
- +Modern, focused UI built around the treemap. TreeSize is feature-dense and IT-admin-oriented — that's the right tool for that buyer, but it's heavy for a person who just wants to see what's eating their drive.
- +Cross-platform mental model. Diskaroo behaves the same on Mac, Windows, and Linux — same shortcuts, same workflow, same collector tray. TreeSize is purely a Windows tool.

FAQ
Is TreeSize Free enough?+
For a Windows-only home user who just wants a treemap and basic visualization, yes — TreeSize Free is a solid option and it costs nothing. Diskaroo is paid up front but covers Mac, Windows, and Linux under one license and ships byte-exact duplicate detection.
Does Diskaroo replace TreeSize Professional for IT admins?+
No — and we're not pretending to. TreeSize Professional is built for network-share scanning, NTFS permission reports, scheduled scans, command-line automation, and custom report exports. Diskaroo doesn't ship any of those features. Different product, different buyer.
Does Diskaroo find duplicates as well as TreeSize?+
Different approach. Diskaroo's three-pass byte-exact match (size group, 64 KB partial hash, full-file hash) prioritizes correctness — a flagged duplicate is identical down to the byte. TreeSize ships duplicate detection from the Personal tier up; both will catch real duplicates.
Can I scan a Mac volume with TreeSize?+
No. TreeSize is Windows-only. If you need cross-platform parity in one license, Diskaroo runs on Mac, Windows, and Linux from a single $19.99 lifetime purchase.
Does Diskaroo do scheduled scans like TreeSize Professional?+
No. Diskaroo runs every scan manually — it has no scheduling. TreeSize Professional has had scheduled scans for years and does it well. If automated scheduled scanning is your primary requirement, TreeSize Professional is the better tool.
