Daily Mac App: WhatSize
Getting to grips with the files and folders on your hard drive can be a chore, but the right tool makes it easier. WhatSize is a tool that combines the best of several disk visualisers into one package. WhatSize scans your disk(s) and reports on the size of your files and folders with a straightforward, color coded, Finder-esque presentation. From there you can click through folders, drilling down to large problem areas, identifying files and folders was you go. WhatSize can also give you a pie chart representation of your data with labels and concentric folder display. For instance, your home directory is held within the "Users" folder on the root of the drive, so the Users folder is displayed in the innermost ring, while your home directory is displayed on the next ring out. You can drill down by double clicking folders, or zoom out by double clicking on white space. It's simple and intuitive. There's also a table view that you can sort by file size, or you can scan for duplicates, which scans and compares your files, which takes a while (read: hours) if you have lots of files, but then allows you to easily see what's doubled up. WhatSize will also let you scan files and folders with Administrator status, allowing you to scan other users data on your drive. If you're looking for a comprehensive, simple disk space visualiser, WhatSize does the job admirably for US$12.99 and is available from whatsizemac.com. But don't take our word for it, download the free trial and give it a whirl. Thanks to Klajd Deda for the suggestion.
DaisyDisk 2.0 offers scanning multiple discs, in-app deletion
In a moment of great minds thinking alike, as TJ Luoma was writing up his Mac 101 on tracking down hard drive space hogs, I was contacted by the folks at DaisyDisk to see if I wanted to take version 2 of their data visualization software for a spin. The core of DaisyDisk is the same as when I first reviewed the software in July 2009. It took roughly six minutes for it to scan my 640 GB drive and display the results in a daisy wheel. The UI was rewritten on Core Animation and it shows. Animation is smooth, and colors are vibrant.
Easy visualization with Daisy Disk
Daisy Disk is the perfect example of one of those tools that should be built right into OS X. It's the latest in disk visualization utilities -- software that scans your hard drive and lets you know which files are being hard drive hogs (in my case, World of Warcraft - no big surprise there). But, it's the added features that turn this from basic to "wow, why didn't Apple develop something like this?" Once you initiate the software, you'll see a list of mounted drives on your network that you can scan. I scanned my main drive. It took less than four minutes for it to go through the 120GB drive and display everything in a circular graphic that does remind you of a daisy wheel. Each section of your drive is color-coded for its specific purpose. The closest parts to the center of the graphic are the root levels. Going further out will net you very specific details on file sizes. Clicking on one section move it to the forefront and let you see everything on that level. When you get down to the files themselves, tap the space bar to preview the file. Then, right click to expose those files in the Finder, then do what you wish with them. Then, click on the inner circle to go back out to the level above. For smaller files and folders, it's better to use the list on the side rather than try to pick things out of the wheel. Doing this enabled me to find large files that I hadn't seen in years, including a folder of old backups from 2006 that got carried over from my iBook. Deleting those netted me 7GB of space. The only feature really not working properly is the preview portion. When I tried playing .M4V video sources, I was rewarded with a grey screen. Regular .AVIs were fine. DaisyDisk costs $19.95USD and requires OS X 10.5 or higher. You can do a full-featured download for free, which gives you a great taste of what it has to offer. For those wanting the same sort of tools, but for free, give OmniDiskSweeper or GrandPerspective a try.
