Info & Features

Measure

WhatSize quickly measures the size of your storage devices and allows you to sort, filter, and refine the results. The files and folders are automatically sorted by size to show the largest first. The app uses the latest macOS technologies to stay up to date with any changes without having to re-scan everything.
Column View

Visualize your disk usage with the familiar Finder Columns View. Click on a directory to drill down for more detail.
Cleaning Tools

Intelligent tools help you find space-wasters and remove them with a single click. Let WhatSize clean up log files, downloads, caches, temporary files, and application clutter such as unneeded translations in languages you don’t speak. Reclaim space and speed up your Mac.

Or you can always start a free trial!
