JkDefrag is a magnificent defragger and optimizer for hard drives, but it has one main weakness, and that is you can only configure it via the Windows command line. This is a tedious and sometimes boring job. For this reason a tool like Turbo Defrag has been created.
The aim of Turbo Defrag, which is totally free, is to let you configure JkDefrag in a much more easy, visual, and intuitive way. This way you can do defrags of your hard drive simply and quickly.
Logically, to use Turbo Defrag you need to previously install JkDefrag.
