A treemap of the whole tree
Every folder drawn at the size it actually occupies. Big things look big. Click to descend, and the way back up stays visible.
See what's using your space.
Recover what you don't need.
A native macOS storage analyser that measures every folder, draws the whole tree as a treemap, and finds duplicates by comparing file contents rather than names. Nothing is removed unless you select it, and everything it removes can be put back.

What it does
Measurement first, removal second
Most disk cleaners lead with a number they want you to click. This one leads with where the space actually went, and lets you decide what happens next.
Duplicates verified by content
Copies are found by hashing the bytes, not by comparing names. A renamed photo is still caught; two different files that share a name are not called copies.
Nothing goes without a reason
Every candidate for removal carries what it is, what it costs to lose, and how confident the app is. Protected items are shown and never selectable.
Reversible by design
Removals are recorded in a ledger and can be restored from it. Undoing the app's own work is never a paid feature and never will be.
Applications, and what they left behind
Uninstall an app together with its caches, containers and preferences — each one listed, each one reviewable, each one yours to keep or drop.
Figures you can check
Sizes are measured, not estimated, and what the scan could not read is reported rather than quietly folded into "Other".
The app
Every screen it has
Storage Explorer is the one above. These are the other four, shown from MacDiskCleanUp Insights, the Mac App Store edition. The figures in them are sample data.
Two editions
One of them cleans. The other cannot, by design.
The Mac App Store requires apps to run in a sandbox, and a sandboxed app cannot remove another app's files. Rather than ship a cleaner that quietly fails at cleaning, there are two builds and each is honest about what it is.
MacDiskCleanUp
The full app. Signed and notarised by Apple, installed from a disk image.
- Scans your whole Mac
- Treemap, large files, duplicates
- Cleans caches, logs and Trash
- Uninstalls apps with their leftover files
- Restores anything it removed
MacDiskCleanUp Insights
The same scanner and the same screens, read-only. It measures the folders you choose and changes nothing.
- Measures folders you pick
- Treemap, large files, duplicates
- Cannot clean anything
- Cannot uninstall apps
- Sandboxed and read-only, enforced by macOS
Pricing
Free does the analysis. Pro does the tedious parts.
The whole measurement is free, permanently — every screen, every figure, and the cleaning of the safe and obvious things. Pro pays for the work that has to be maintained release after release.

Purchasing is not open yet. The app is finished and the licence system
works; what does not exist yet is the checkout. Nothing on this page can be bought
today, and no page here collects payment details. Email
support@a4teams.com and you will hear when it
opens.
If Pro lapses, the app does not lock. An expired licence drops back to
the free tier and everything free keeps working. Restoring files the app removed stays
available in every state — expired, refunded, or never purchased. Undoing our own
destructive action is not something to sell.
Questions
The ones worth asking first
Will it delete something I need?
Nothing is removed unless you select it and confirm it. Items the app considers unsafe to touch are shown but cannot be selected at all. Everything it does remove is recorded and can be restored. The App Store edition cannot remove anything under any circumstances — macOS enforces that, not our good intentions.
Why are there two versions?
App Store apps must run in a sandbox, which blocks an app from touching another app's files. That makes cleaning and uninstalling impossible there. Rather than ship a crippled cleaner, the App Store edition is a read-only analyser and says so, and the full app is distributed directly, signed and notarised by Apple.
Does it send anything anywhere?
No. There is no account, no analytics, no crash reporting and no network access in either edition. What it measures stays on your Mac. See the privacy policy, which is short for exactly that reason.
Why does the full app ask for Full Disk Access?
Because macOS puts caches, logs and application support files behind that permission, and an app that cannot read them cannot tell you they exist. You grant it in System Settings, and you can revoke it at any time — the app keeps working with less to show.
Is "lifetime" really lifetime?
It covers the app for as long as it is maintained, including future major versions — there is no upgrade fee planned. It is not a promise that any software runs forever on operating systems that have not shipped yet, and nobody honest can make that one. The exact terms are in the terms.
What happens to my files if I stop paying?
Nothing. Your files are yours and the app never holds them. Pro features stop; scanning, the treemap, cache and log cleaning, and restoring anything previously removed all keep working.
