Cleaning up your Mac with Drive Genius 3 is a great way to get your Mac running smoothly and prevent further drive issues from becoming a bigger problem.  DriveSlim™ is a great tool to help recover drive space by deleting or archiving large, duplicate, or unused files. Through DriveSlim’s various slimming plans, Drive Genius 3 will detect and recommend files that can be deleted from your system to help free space on your hard drive. DriveSlim™ can help you determine what files can be deleted when your hard drive gets near its full capacity. DriveSlim™ works only on user files. These are the types of files that DriveSlim will focus on and find.: Large Files: Finds files that are greater than a set minimum size and have not been accessed in a period of time you specify. The detected minimum size can be from 5MB to 100MB. The period of time can be 0 to 365 days.

Duplicate Files: Finds any files that are greater than a set minimum size that have duplicates. The detected minimum size can be 0MB to 100MB. You have an option to replace any duplicates with an alias pointing to the original file.

Unused Localizations: Finds all localized resources for any applications and allows you to specify what languages you want to keep. This will help delete any unnecessary language files from your applications. You can select any other languages to be kept by marking the selected language.

Universal Binaries: A Universal Binary is a container for multiple application binaries, each optimized for a specific CPU. For any given application, there are up to 4 possible binaries in one file (Intel, Intel 64-bit, Power PC, PowerPC 64-bit), which your machine uses to run the application. Intel-based Macs do not need PowerPC binaries, and vice versa. DriveSlim detects and deletes any unnecessary binaries that your computer hardware cannot run. If you are using a 32-bit system, you can choose to keep 64-bit binaries by enabling “Keep 64-bit variants” in the Slim Options. If you are using a 64-bit system on Mac OS X 10.6 or greater, you can choose to keep 32-bit binaries by enabling “Keep 32-bit variants”. At least one option must be enabled (64-bit or 32-bit).

Cache/Temporary Items: Finds all cached and temporary files that have not been accessed in a period of time you specify. The period of time can be set from 1 to 31 days.
