DiskWise: Storage Cleaner
See where your storage went
Only for Mac
Free
Mac
Drill into any folder level by level, keep free space in the menu bar, and switch between ten languages.
DiskWise is a disk cleaner that shows you the picture first. It won't "optimise" your Mac behind your back or claim you have hundreds of gigabytes of junk. It lays out where your storage actually went, and you decide what goes.
How it differs from other cleaners
· Nothing is deleted automatically. Every page is a list you read, tick and act on. There is no one-click "optimise" button whose effects you can't inspect.
· Trash only. Removals move items to the system Trash, and you can undo them one by one inside the app. Emptying the Trash stays a separate step you take in Finder: the app opens the Trash window for you, you press ⌘⇧⌫ and confirm. It never deletes permanently on its own, and it doesn't ask for permission to control Finder.
· Deleting takes two presses. On the overview, the first click on a segment only arms it; click again within 3 seconds to actually move it, and the arm drops itself when the timer runs out.
· Protected paths. Critical system locations, apps in use and your photo library are flagged so they can't be swept up in bulk.
· The numbers add up. Every sidebar entry carries the size it measured, and a page header total is the same number as the rows on that page — when it can't be, the app says "Showing the 30 largest of the 152 found" instead of quietly disagreeing with itself.
What it finds
· Overview: a ring gauge for disk usage with the biggest folders ranked below it. Tap any row and the breakdown for that row opens right there, while the ring shrinks to a small reference — no page flip.
· Large Files: the biggest files the scan reached, ranked by size, with how many rows to show up to you (30 by default, 200 at most), and a switch to skip dev folders such as node_modules. Any folder in the results drills down one level at a time, with a breadcrumb and a way back up.
· Long Untouched: files you haven't modified in a long time — usually the safest to drop.
· Duplicates: grouped by content hash, with the comparison threshold up to you (20 MB and up by default), keeping the newest copy of each group and only offering the rest — backup and export folders are dated in ascending order, so keeping the oldest would throw away your freshest copy.
· Dev Caches: one page for the caches and archives that development tools leave behind — Xcode, iOS simulator devices, Gradle, npm, Maven, conda, bun — each row marked Safe or Careful. Simulator devices are listed one per row, so you can see what each one costs.
· App Caches: a built-in knowledge base of common caches (browsers, dev tools, design apps), each entry explaining what it is and what happens if you clear it.
· Leftovers: preference and cache files orphaned by apps you already uninstalled.
· node_modules: every frontend project's dependency folder in one list, with the package manager read off each project's lockfile — delete it, install again later.
· Docker Usage: a read-only view of image, container and volume sizes; OrbStack is recognised too. Totals add up real disk usage only, so a thin-provisioned virtual disk isn't counted at its quoted size, and it never runs Docker commands for you.
· Trash: what this session moved in, and how much of it is still undoable. The sandbox can't read the Trash folder itself, so the app says so instead of showing you a fake zero.
Also
· Ten interface languages (English, Chinese, German, French, Spanish, Portuguese, Russian, Japanese, Korean), light and dark, and six skins editable in skins.json.
· A menu bar readout shows free space at a glance, with optional launch-at-login.
· Fully offline: no network access, no accounts, no analytics, no crash reporting, nothing uploaded.
· The Mac App Store build runs inside the macOS sandbox. On first launch you grant it one folder to scan (usually your home folder). It reads directory metadata only, and you can revoke the grant in System Settings → Privacy & Security.

What's new in 1.7
See inside a folder
• Big Files and Old Files now drill into any folder level by level, with a full breadcrumb and an up-one-level button, so you can see exactly where the space went.
• Folders a level could not measure stay in the listing and are labelled as such, instead of vanishing from the total.
• Each folder row also shows what the built-in knowledge base knows about it.
Delete prompts that say what you are deleting
• Every confirmation now names the specific thing you are about to remove, instead of one generic warning.
• The careful badge is split in two: safe to re-download, versus a real data loss risk.
• Removed files fly to the Trash, and every page you drill into has a visible way back.
Menu bar
• A menu bar item shows your free space at a glance, with an optional launch-at-login setting.
Ten languages, editable skins
• The app now ships in ten languages, switched from the globe in the toolbar.
• The skin list moved into an editable skins.json.
Fixes
• WeChat 4's new media locations are recognised.
• Layouts no longer break at the minimum window width.
