WhatSize Icon

WhatSize is a file system utility that allows you with a chart display, to easily drill-down and discover how your disk space is being used. WhatSize measures the size of your hard drive and allows you to sort, filter, and refine the results. WhatSize will cache measurements for speed and will use Apple’s FSEvents to merge file system changes in real time.

Moreover, it also identifies duplicate files on your system so that you can move them to trash, replace them with hard links or simply delete them immediately.

Key Features:

  • Fast performance
  • Discover how your disk space is being used
  • Clean up system unused files
  • Identifies duplicate files on your system
  • Filter Results
