In the context of administering computer systems, defragmentation is a process that reduces the amount of fragmentation in file systems. It does this by physically organizing the contents of the disk to store the pieces of each file close together and contiguously. It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Some defragmenters also try to keep smaller files within a single directory together, as they are often accessed in sequence.Disk Defrag will speed up your computer by optimizing file system. It can defragment files, consolidate free space and move system files to the faster part of the disk.With AML Free Disk Defrag you'll get the maximum out of your hard drive performance.
