UnpackX is a very easy to use application that allows you to comprehensively work on disc images and file archives.
Use UnpackX to unpack disc images (BIN, DAA, ISO) and file archives (RAR, RAR parts, 7z) into folders. NOTE: UnpackX1.0.0 will remain functional until April 1, 2011. After this date, you cannot launch it. If necessary, rewind the system clock to a date before that date.
NOTE: UnpackX 1.0.2 can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
To access the previous UnpackX versions you can go to the developers project page HERE. The page provides access to UnpackX 1.0.0 version (suitable for Mac OS X 10.5 or later)
