See what's eating your disk.

StorageScope is a free, open-source disk space analyzer for macOS. It ranks large folders, stale files, and SHA-256-verified duplicates, then plans cleanup you confirm — without uploading a byte.

v0.7.1

Roomier windows and keyboard-first cleanup

Full changelog →

Better default windows

Main and Settings windows open with more practical dimensions, keeping dense controls and review panels visible.

Keyboard cleanup flow

Cleanup Review supports keyboard movement and selection so verified reclaim can be reviewed without constant pointer travel.

Folder-tree reveal

Selection and reveal behavior now keep the folder tree, sidebar, and detail pane in sync across navigation paths.

Steadier tables

Item rows and columns were tuned for clearer scanning, predictable keyboard focus, and less visual churn.

Polished view states

Overview, duplicate review, type breakdown, tree, and empty/loading states read more cleanly at a glance.

Regression coverage

New app-level tests cover keyboard selection, folder-tree reveal behavior, and tree navigation state.

Features

Everything you need to reclaim disk space

A macOS disk space analyzer, storage cleaner, and duplicate file finder in one sandboxed app.

macOS disk space analyzer

Rank largest folders, old large files, file types, installers, archives, disk images, caches, and build artifacts.

Mac storage cleaner planning

Separate verified duplicate reclaim, review-suggested cleanup, and access gaps before anything moves to Trash.

Duplicate file review

Start from same-size candidates, verify matches with SHA-256, and keep hashing work bounded to what you need.

Parallel, performant scans

Recurses sibling directories concurrently and scales hash verification with available cores, with deterministic child order.

Keeper comparison

Side-by-side sheet lets you reassign the keeper of a verified duplicate group with size, date, and path at a glance.

Transactional Trash

Batch moves go to Trash via macOS APIs and roll back earlier moves if a later one fails — never silent permanent deletion.

How it works

Three steps to a cleaner Mac

Grant folders

Pick folders through macOS folder selection or persist access with security-scoped bookmarks. Nothing is uploaded.

Scan and review

See ranked storage pressure, file types, and verified duplicates with a keeper per group, then mark cleanup candidates.

Send to Trash

Confirm a batched, transactional move to Trash that rolls back on partial failure. You stay in control of every change.

In the app

The whole picture, one window

Ranked storage views, cleanup review, folder tree, and inspector — the same scan, four ways to read it.

Nothing leaves this Mac

StorageScope never sends scan data off your machine. It is sandboxed, MIT licensed, and small enough to read every line.
