Common questions
When should I choose DaisyDisk?
A good fit for Mac users who want a sunburst, cloud connections, and snapshot tools. One-time license; free trial. Check vendor pricing and direct/App Store edition differences.
When should I choose OmniDiskSweeper?
A good fit for Mac users who prefer a free size-sorted browser to a chart. Free download from The Omni Group.
Will both apps show the same size?
Not necessarily. Match the scan root, permissions, exclusions, and logical/allocated-size mode. Hard links, APFS clones, snapshots, sparse files, and cloud placeholders can change totals. A reported size is not a guaranteed amount recovered after deletion.
