O&O Defrag Professional

O O Defrag Professional Boxshot

O&O Defrag Professional optimizes your hard disks and SSDs, and you can experience speed increases of up to 100%! Regular disk defragmentation optimizes your PC performance. When you defragment, the files that Windows splits up when saving documents across the hard disk or SSD are put back in order again so that files can be quickly recognized and found by the SSD or the read and write heads inside your HDD.
