VolumeLens

See what is using your Mac's storage.Decide what goes.

Point VolumeLens at a folder or a whole volume. It maps where the space actually went, explains the usual suspects, and moves only what you choose to the Trash.

Free to scan, browse, search and clean up · macOS 14 Sonoma or later

The VolumeLens storage map: a large file fills the left half, and folders on the right are drawn as labelled containers with their own contents nested inside.

Nothing leaves your Mac

There is no network code in the app. No account, no sync, no telemetry. Turn off Wi-Fi and every feature still works.

Nothing is deleted

The only action is Move to Trash, after a review sheet that lists exactly what will go. Restore from the Trash until you empty it.

Numbers you can trust

Hard links counted once. Sparse and compressed files flagged. Folders macOS won't let us read are counted, not silently zeroed.

How it works

Three steps, and you stay in control at every one

No wizard, no automatic sweep, no surprises.

  1. 01

    Choose a folder

    macOS asks you to pick it. That choice is the permission — VolumeLens can only read where you point it, and only names, sizes and dates.

  2. 02

    Read the map

    Folders are drawn as containers holding their own contents. Hover for detail, double-click to go deeper, zoom into a crowded corner, or switch to the list.

  3. 03

    Move what you choose

    Select one item or many, review exactly what will go and what is blocked, then send it to the Trash.

The map

Structure, not a wall of boxes

Most storage tools flatten a folder into one layer of rectangles. VolumeLens draws folders as containers, so you see how a project is actually shaped before you touch it.

  • Four levels of nesting at once, each labelled with its name and size
  • Hover any cell for kind, size, item count and where it sits
  • Pinch or ⌘+ / ⌘− to zoom, then scroll to pan
  • ⌘-click to select several items and act on them together
  • Colour by kind or by age; measure by size or by space used on disk

Insights · Pro

The usual suspects, explained

A pass over your scan that recognises where Mac storage typically goes — and tells you what each thing is before you touch it.

  • Dependency folders, build output and Git history
  • Xcode DerivedData, archives, device support and simulators
  • Caches for Homebrew, npm, pnpm, pip, Cargo, Gradle, Maven, CocoaPods
  • Docker's disk image, VM disks, installers and large video

Every card says what it is, why it grows, how it was matched, and how risky removal is. High-risk items are explained but never offered for one-click removal.

Safety

Careful by construction

The safety rules are in the code, not in the marketing copy.

Re-checked before anything moves

Files change between a scan and a decision. VolumeLens re-reads each item immediately before moving it and refuses anything whose identity, size, kind or timestamp no longer matches.

Places it will not touch

System locations, installed applications and sensitive Library folders like Mail and Keychains are blocked with an explanation. So is the inside of a package.

No helper, no hidden access

It runs in Apple's App Sandbox with read access only to what you selected. No privileged helper, no background daemon, no admin password.

A log you can check

Every move is recorded on your Mac with its outcome, including the ones that were refused and why.

Pricing

Questions people ask first

Does it upload anything?
No. There is no network code in the app at all. Disconnect from Wi-Fi and scanning, searching and cleanup work exactly the same. The only thing that leaves your Mac is a support message you write yourself.
Will it delete something I need?
It cannot delete anything. Items move to the Trash, after you review a list of exactly what will go and tick a box confirming it. You restore from the Trash like any other file.
Is it a subscription?
No. Pro is ₹999 once, for up to 3 of your Macs. Scanning, the map, the list, search and cleanup are free forever.
Why are my totals different from Finder?
Finder and VolumeLens count differently in ways that matter: hard links, sparse files, filesystem compression, and folders macOS will not let an app read. VolumeLens shows both nominal size and space used, and tells you when a total is a lower bound.
Who makes it?
Onzira Labs Private Limited, a software company registered in New Delhi, India.
