Baobab (Disk Usage Analyzer): what stands out
A good fit for Linux desktop users who prefer a GNOME application with graphical disk analysis.
Baobab (Disk Usage Analyzer): strengths
- Tree and graphical folder-size views
- Scans devices, selected folders, and online accounts
- Free software maintained within GNOME
Considerations
- A Linux desktop app rather than a native Mac application
- Remote access depends on available account/backend support
- A scan inventory is not a backup or deletion recommendation
OmniDiskSweeper: what stands out
A good fit for Mac users who prefer a free size-sorted browser to a chart.
OmniDiskSweeper: strengths
- Largest-first file and folder browsing
- Open items or move them to Trash
- Official downloads include versions for older Macs
Considerations
- Column browsing rather than a graphical disk map
- Check the download requirements for your macOS version
- The cited overview does not document saved reports or duplicate matching
For a useful comparison on your own drive, match the scan root, access permissions, and size mode. Chart style changes how you explore the results; it does not by itself establish measurement accuracy.
Common questions
When should I choose Baobab (Disk Usage Analyzer)?
A good fit for Linux desktop users who prefer a GNOME application with graphical disk analysis. Free software from GNOME; available through Flathub/distributions.
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.
