WhatSize overview

WhatSize allows you to quickly measure the size in bytes of a given folder and all subfolders and files within it. You would be surprised at how many useless files might be laying around on your hard disks. The files and folders are automatically sorted by size, with the biggest sizes first. WhatSize helps find out what files are taking up all of that space. Then it makes it really easy to remove or move those files. You'd be surprised how many useless files are lying around on your Mac's hard disk.

While the app is measuring a folder the user can browse the files within that folder and immediately see the size in bytes. Hidden files, cache files, directories will all show up with their corresponding size. This application is similar to the ancient NeXTSTEP, DarkForest.

Once the measuring of a folder has ended the user can also view the information by filtering for particular file sizes or types. The user can also move unwanted files and folder in the corresponding Trash bin similar to the Finder's Delete button.

It's a CRASHER on my M1 MBA. It's still not ARM native. I've uninstalled it. Better utilities duplicate its use anyway. Bye-bye!

Bought a second license for my MacBook Air. With a small SSD I wanted to make sure I used my storage carefully. When I loaded the dropbox app I noticed a decrease in storage using Whatsize and quickly deleted the app to regain storage. Dropbox wasn't configured properly and Whatsize saved me a bit of agrevation.

I discovered this when it was freeware and loved it. The developer was prolific and generous. When he sold WhatSize and it became payware, I backed off until I saw a plea from the new guy about how rough it was for him, his wife and new baby to make it on the income from WhatSize, so I bought a license. I've used Daisy Disk since it came on the scene so don't know what's up with WhatSize except it doesn't do anything it didn't do when it was Peter's freeware. Freeware to $30 a pop. No, thank you.

I've been using WhatSize since version 5. It's great software to keep up with the usability, performance, and hence the life of your storage devices. I absolutely recommend it !!

It's my go-to app for finding out what is using up disk space. Glad it's been updated to work with Mohave!
