The Omni Group has released an OS X bases system utility, OmniDiskSweeper. The new program allows users to easily view files on OS X and OS 9 disks and partitions to examine which files are taking the most space, thus making it easier for users to manage their drive space. According to The Omni Group:
OmniDiskSweeper 1.0 beta 1 is now available. OmniDiskSweeper is a Mac OS X application for making space on Mac OS X, Mac OS X Server and Mac OS 9 disks. This new addition to the Omni Groupis product line is a native Mac OS X application, written in Objective-C with Appleis advanced Cocoa frameworks, and requires Mac OS X Developer Preview 4.
On launch, OmniDiskSweeper displays a list of the disks attached to your machine. (If your disks are partitioned, OmniDiskSweeper lists each partition separately.) If you double-click on a disk, a window opens with a file browser showing all files and folders on that disk, sorted by size. This makes it easy for you to see what files and folders are taking the most space. OmniDiskSweeper lets you delete the files and folders you no longer want, and automatically recalculates and reorders the files and folders as appropriate. (As always, make sure you donit delete anything you or the system actually need. You probably shouldnit delete anything in the "System" folder, for instance.)
The current beta version of the program is available for free, and will expire January 1st, 2001. Pricing for the final version has not yet been set. You can find more information at the Omni Group web site.
