What OmniDiskSweeper does well
The Omni Group describes it as a way to list drive contents largest-first and quickly open or move unwanted files to Trash. That linear view is easy to understand and the utility is free.
What Storage Map adds
- A proportional treemap for seeing several large branches at once
- Allocated and apparent size views with hardlink deduplication
- Visible exclusions for protected, custom, and cloud-provider locations
- A menu-bar capacity reading, alerts, and 90-day local history
- Finder reveal, Trash, and guarded permanent deletion
- An optional terminal interface backed by the same Rust scanner
Which interface is easier?
A sorted list is excellent when you want one unambiguous next folder. A treemap is better when spatial comparison helps you understand the whole disk. Storage Map deliberately offers both hierarchy and visual context rather than asking one view to do every job.
