OmniDiskSweeper
OmniDiskSweeper is a macOS disk space analyzer that helps you find large files and folders so you can review storage use and free space.
What is OmniDiskSweeper?
OmniDiskSweeper is a native macOS utility for examining disk usage and finding the files and folders that take up the most space on a Mac. It is designed for users who need a clear, size-sorted view of storage when a startup disk is getting full or when they want to locate large items quickly. The app scans a selected drive or folder and lists contents from largest to smallest, which makes it easier to spot old downloads, media files, archives, and other bulky items. You can open items from the results and send unwanted files to the Trash from within the app. Published by The Omni Group, OmniDiskSweeper fits best in cleanup and storage-review workflows where users want a simple utility instead of a full maintenance suite.
Key features
- Scan a drive or folder to measure disk usage
- Sort files and folders from largest to smallest

Safety overview
Status: Mostly safe
OmniDiskSweeper is legitimate disk analysis software from The Omni Group. Its access to files and folders is consistent with its purpose, and broader file visibility may depend on the macOS permissions you grant it. Use normal care before deleting anything it finds, especially items in Library, System, or other unfamiliar locations, because removing the wrong files can affect apps or macOS behavior.
Recommendation: Keep OmniDiskSweeper if you actively use it to inspect storage and find large files. If you no longer use it, removing the app is generally fine and only takes away its disk-scanning features. Before deleting files through the app, review each item carefully and prefer moving files to the Trash rather than permanently deleting them.
