Choose a disk or folder and see file counts, categories, and discoveries while scanning. Explore the space map, search by name, or filter the largest files by type, size, and modification date. Review the safe-to-delete and needs-review groups before moving your selection to Trash. File names and sizes are sample data; the video is not a scan benchmark.
From finding it to sorting it out
A clearer way to tidy up
Start with the whole disk. Follow the space down to individual files, then decide what to keep.
Find the files that matter
Search by name, or filter by type, size, and modification date. Check a selected file with Quick Look.
Combine type, size, and modification filters to narrow your review.
Review before you remove
Review grouped suggestions for caches, build output, and older files. Check the details before moving your selection to Trash.
See the reason and file details. You decide what stays and what goes.
You stay in control
Clear about the numbers. Careful with your files.
Measure local disk usage
Cloud-only files are counted by their local disk footprint. Available space can also depend on APFS shared data, snapshots, and Trash.
A check before cleanup
Suggestions are grouped into safe to delete and needs review. Check individual items before they go to Trash, where they can be restored until permanently deleted.

Frequently asked
A few things to know before downloading.
How long does the free version last, and what is limited?
No time limit. Scanning, visualization, browsing and preview are free forever, and your results don't disappear. «Move to Trash» is free for up to 1 GB in total; beyond that, and for «Show in Finder», you need to activate. Activation is a one-time purchase.
Does moving files to Trash free up space?
Not yet. Files in Trash still occupy disk space, but can be restored. Permanently delete them once you are sure. System-reported free space may also be affected by snapshots and other factors.
How is my data and privacy handled?
Scanning and file analysis run on your Mac. File contents, names, and paths are not uploaded. License checks and app updates connect to their respective services.
How are 5 devices counted? What if I switch Macs?
Each activation takes one slot. Before switching Macs, go to Settings → License → Deactivate this device to free the slot, then re-activate on the new Mac. Reassign anytime.
Which macOS versions are supported?
macOS 14 Sonoma and later. Universal binary — both Apple Silicon and Intel run natively.
Are future updates really free?
