OmniDiskSweeper is a freeware disk space analyzer utility for macOS developed by The Omni Group, which recursively searches a filesystem and displays entries sorted and color-coded by size, from largest to smallest. Alternatives include DaisyDisk and GrandPerspective.[2] [3] [4]
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, though 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, though 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.[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]
