The Sovapps team has introduced Precious Disk 1.0 (http://tinyurl.com/lltnnbq), a hard drive utility for Mac OS X. It scans your disks and folders and allows you to get more space by tracking and reviewing all your file content.

You can locate all your hidden files thanks to special filters. Before moving them to the trash, you can view them in the Finder or Quick Look.

Precious Disk requires OS X 10.8 or later and costs US$9.99. It’s available at the Mac App Store in the Utilities category.
