What WhatSize is
WhatSize is paid macOS software for examining storage across files, folders, and applications. It reports application sizes and provides file-type breakdowns, helping you inspect how space is distributed. Its scan scope includes files, folders, and apps, and it can also scan external drives. Reports can be exported for later reference or sharing. WhatSize does not include a treemap view, so its listed analysis is based on item sizes, locations, and file categories instead. The WhatSize plan costs $14.99 a month, with a 30-day trial available. There is no free plan. The application is offered through the WhatSize website and is listed for macOS desktop use. These tools provide several ways to review storage before deciding which files, applications, folders, or external-drive contents need attention.
