Frequently asked questions
What is SpaceOnMyDisk?
SpaceOnMyDisk is a macOS disk space analyzer that scans your drive to show what's taking up room, so you can free up space fast.
Is the scan fast?
Yes! SpaceOnMyDisk uses a parallel scan engine to analyze your disk quickly, even on large drives.
Can it delete files for me?
It moves items to the Trash rather than deleting them outright, so you always get a chance to review and recover before emptying it.
Does it work from the command line?
Yes, there's a CLI mode (--scan) for those who prefer running a scan from the terminal.
Is my data private?
Absolutely. SpaceOnMyDisk scans and analyzes everything locally on your Mac, with nothing sent anywhere.
Is it free to try?
Yes, you get a free 7-day trial, then can choose a monthly, quarterly, annual, or lifetime license.
