Quicksys Disk Defrag is a free disk defragmenter and optimizer for Windows. It 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 Disk Defrag has a system called QSICA (Quicksys Intelligent Clusters Allocation) for clusters optimization.
QSICA is a set of intelligent algorithms capable of detecting the best location of the fragments of a file. Furthermore, QSICA tries to fill clusters at maximum extent with fragments of files already on the disc. As a result, the new files that are inserted in the disc does not try to put fragments in these clusters because they have no space, forcing the file to use free space of the disc, preventing further fragmentation. The process of optimization may take a longer time than other software, but ensures that your disk is organized with the files as best as possible and be prevented to a maximum of further fragmentation. Version 1.16 beta includes new GUI, lots of optimizations, and various additions and fixes.
