Quicksys DiskDefrag is high technology freeware software that aims to rearrange the fragments of files on disk, to be continuously and in order, so that the performance and search speed of the disc increases.

Besides defragmenting the disk, Quicksys DiskDefrag has a system called QSICA (Quicksys Intelligent Clusters Allocation) for clusters optimization.

Defragmentation reduces data access time and allows storage to be used more efficiently. With all the data organized, the head of reading, which is responsible for finding, reading and writing of files on disk need to move less, and the fragments of files are found more quickly. This is directly reflected in the performance and agility of the computer.

The optimization of clusters using QSICA provides maximum prevention that new files inserted on the disk are fragmented and best clusters location.
