Disk Expert is a new disk space analysis and management tool for the Mac that’s designed to help you organize your hard drive content and free up disk space. It requires Mac OS X 10.6 or higher, costs US$14.99 and is available worldwide exclusively through the Mac App Store in the Utilities category.

Disk Expert visually displays the file system usage and allows you to work up the content of the drive and free up disk space. The app enables you to analyze and manage a disk’s content usage and volume by moving items from the disk to a special list from which they can be transferred to another drive or even deleted.

Users can preview a file using QuickLook and view details regarding the system’s information of the file with one click. Disk Expert supports HDD drives, CD and DVD discs, removable USB drives, mounted and even SMB disk images.
