Understand the selected storage scope
Measured categories, folders, files and available application footprints help explain what the authorised scan can observe. Coverage gaps remain visible rather than being treated as empty storage.

Mac Storage Intelligence
Understand your storage.
See what uses space on your Mac, explore scanned folders, compare storage changes and review evidence before taking cleanup action.
Move from a storage total to the files behind it. Scan an authorised folder or drive, explore the indexed results and understand where the measurements come from before deciding what to change.

What you can do
- Choose storage and start with a prominent Scan Storage action beside capacity information.
- Explore measured categories, folders, files and application footprints where available.
- Search indexed names and paths, and inspect large files and storage relationships.
- Compare completed scans with the same scope to see what changed.
- Review duplicate evidence, potential reclaimable items and cleanup selections before acting.
- Read scan coverage and access gaps instead of treating inaccessible storage as empty.
- Keep local scan history and export reports for further review.
- Use Light, Dark or System appearance, with optional numbered guidance.
A clear path from start to finish
- Select the drive or folder you want to understand.
- Grant access and scan the selected scope.
- Explore a category or file, inspect the evidence and review any proposed action.

Know what to expect
A folder scan measures the selected accessible scope, not the entire volume. APFS shared blocks, snapshots, protected locations and filesystem overhead can make file attribution differ from volume usage. Reclaimable space is not a guaranteed saving. Partial scans are marked and are not complete comparison baselines.

Features in practice
The feature list describes the available tools. These examples explain how they support a practical workflow, what to review and where the limits matter.
Find where to investigate next
Search indexed names and paths and inspect large files or storage relationships to identify useful next steps. Category totals do not by themselves identify files that are safe to delete.
See recorded changes
Compare compatible completed scans of the same scope to understand observed growth or removal. Scan history describes sampled observations, not continuous monitoring.
Keep analysis and action distinct
Inspect duplicate evidence and proposed cleanup selections before acting. Local history and exported reports help retain an account of the measurements and their limitations.
Use the compatibility, access and limitation information on this page when choosing a workflow. Sample screenshots illustrate the app; their records and measured results are not a scan of your own Mac.
