Its interface presents a column view similar to the macOS Finder.[5][6] OmniDiskSweeper supports internal and external drives, and network volumes.[7] It warns users when selecting files that are required by macOS or by installed applications, but this only works for applications installed with macOS's Installer utility, based on BOM files.[3]
The program was first released in April 2001 as shareware.[8] Early versions required payment to delete files, but users could also delete them manually through the Finder.[9] The Omni Group relicensed it as freeware in 2009, stating a need to refocus on their other programs.[10]
Specialist outlets MacGeneration and Macworld describe it as a basic tool, useful to find large but unused files.[2][3][11][12] The Register gave it a rating of 70/100, and included it in their 2010 selection of free essential Mac apps.[13]
