DaisyDisk Team has released the public beta of DaisyDisk 2.0, a major update to their award-winning disk analyzer utility for Mac OS X. Disk contents are displayed as an interactive color-coded sunburst map, quickly revealing large files which may no longer be needed, and allowing to delete them. The map can be easily navigated to preview deeper levels of data. The version 2.0 features built-in file deletion, can scan several disks at a time, has brand new UI based on Core Animation, and more.
Co-Founder Oleg Krupnov explains:
The need to delete files from within the application has been an obvious gap that is finally filled … We have also completely redesigned the UI which allowed more efficient ways of working with DaisyDisk, such as scanning many sources at a time, switching between scanned reports, and other things. The use of Core Animation has made the entire application feel faster and more powerful.
When the application is launched an overview of all mounted disks is displayed, with graphical indicators of how full each is. DaisyDisk supports all kinds of disks. 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%. Multiple disks can be scanned simultaneously. 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. Next, segments can be dragged out of the diagram and dropped into the special “collector” zone for further deletion. While the files remain in the collector, the user can cancel his decision to delete a particular file by dragging it out of the “collector”. On each action, the diagram is updated instantly to reflect the changes. Finally, when all unneeded files have been collected and double-checked, the “collector” can be cleaned up with a single click.

DaisyDisk Team is an independent software development startup, founded in 2009 by Taras Brizitsky of Sarov, Russia, and Oleg Krupnov of Kiev, Ukraine. Although various disk scanning applications were available free, the pair were motivated to create DaisyDisk for their personal use, and to explore the use of graphical representation of data and user interface design.
