A CLOSER LOOK

Understand your Mac’s storage.

Read your storage at a glance.

Choose a cushion treemap, flat treemap, or sunburst view of indexed storage. Larger areas represent larger indexed items, helping you compare where the space goes.

Look closer at large files.

Use Largest to review files found by the scan, or explore Kinds and Age for another view of their contents. Reveal an item in Finder before deciding whether to keep it or move it to Trash.

Understand what the scan covers.

The map uses allocated file sizes where available and reflects items ITM can index. Permissions, excluded personal and cloud-library locations, and app-bundle handling can make the result differ from the volume’s used-storage figure.

IN THE APP

How to find large files on your Mac.

  1. Choose a location.

    Open Disk Space, select the drive or one of the listed folder targets, and start a scan.

  2. Inspect the map and lists.

    Compare larger areas in the map. Use the Largest, Kinds, or Age view to investigate the indexed items.

  3. Review before removing.

    Reveal an item in Finder to confirm what it is. Move to Trash is a separate action you choose; scanning does not delete files.

USEFUL TO KNOW

Disk space questions.

Can ITM help me find large files on my Mac?

Yes. The Largest view ranks files found by the scan, with a current size cutoff of over 2 MB. You can reveal an item in Finder to inspect it.

Does scanning automatically delete files?

No. A scan reads storage information. Moving a file or folder to Trash requires a separate action that you select.

Why can the scan differ from my Mac’s used storage?

The scan reflects indexed items and uses allocated sizes where available. Permissions, excluded locations, and app-bundle handling affect coverage, so the map may differ from the volume’s used-storage total.

Will Full Disk Access make every location visible?

Coverage depends on macOS permissions, and ITM intentionally excludes certain personal and cloud-library locations. Granting broader access does not guarantee complete coverage.
