Version 6.2.1 : Monday June 8, 2015
Implemented the ability to quickly measure separate folders rather than the whole volume. Drop a folder in the left side bar and measure it quickly
Reduced memory usage by a good 15%
Reduced time to open the database by 10%, making the app snapier on launch
Added print button to the tool bar for easy access
Refined activity window to display the current path being measured
Reworked whatsized to use apple's sanctioned XPC interprocess architecture, this will allow for more flexibility for users wanting to scan their drives as Administrator
Fixes to the German translation
Fixed a rare crash related to multiple measures going on in parallel
The app can now scan multiple volumes at once, however if multiple volumes reside on the same disk performance will be affected
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.
