Disk Scanning/Mapping Utility for Mac OS X ($20)

DaisyDisk Team announced the release of DaisyDisk 1.5.2, an update to their scanning/mapping system utility for Mac OS X.

Disk contents are displayed as an interactive sunburst map, quickly revealing large files which may no longer be necessary. The sunburst map provides a quick color-coded overview of disk usage, and can be simply navigated to preview deeper levels of data. Unlike some similar products, DaisyDisk facilitates the removal of a few very large files, rather than many small ones. The 1.5.2 update provides 64-bit support on Snow Leopard, improved scanning speed, and optimized memory footprint.

DaisyDisk supports all kinds of drives, including Time Machine volumes, network share drives, FTP drives, USB thumbsticks, FireWire drives, CD/DVD drives and images, FUSE drives, SATA drives, IDE/ATA drives and RAID drives. When the application is launched an overview of all mounted disks is displayed, with graphical indicators of how full each is. Choosing the Scan button next to any displayed disk begins the scanning procedure, which has been highly optimized, and according to DaisyDisk Team outperforms competitors by 10-50%. The resultant circular sunburst map, in contradistinction to the more frequently used rectangular tree map, consists of color-coded, concentric rings. Mousing over ring segments lists the category of files and folders and their total size (e.g. movies, 85.3 GB). Clicking any segment expands it into a full sunburst map revealing greater detail. The process can be repeated until the user has reached the level where individual files are listed.

Feature Highlights:

• Helps free disk space by identifying large files which may no longer be needed
• Innovative infographics – animated, interactive, color-coded, sunburst map
• Runs as 64-bit application on Snow Leopard
• Highly optimized code performs scanning/mapping faster than most other apps
• Super/root user can scan all files without regard to permissions
• Built-in QuickLook preview of files content
• Free, fully-functional trial version available for download

DaisyDisk also supports scanning in Super-User mode, as a root level user, with access to all files without regard to permissions. In this mode all folders within the home folder of other users’ accounts, which would otherwise appear empty, can be analyzed.

Apple has recognized DaisyDisk as a Staff Pick, and it received an About.com Reader’s Choice Award for 2010 in the System Utility category. In addition to other awards, the app has received consistent praise in more than 100 print and online reviews, published in a variety of languages.

"When we entered the market, it was already crowded with well-established competition, most of them being free apps," stated co-founder Oleg Krupnov. "But we took the risk, because we didn’t like how all those other apps worked and looked, and had a few ideas how such an app could be greatly improved. So we built DaisyDisk as a disk tool to fulfill our own dream."
