O&O Defrag Professional 20.5.603


O&O Defrag Professional Icon

O&O Defrag Professional 20 is a powerful and effective defrag utility, that can optimize your hard disks partitions by reconstructing scattered file fragments, which result in improvement of your overall computer's performance.

When you defragment, the files that Windows splits up when saving documents across the hard disk are logically put back together again so that files can be quickly recognized and found by the read and write heads inside your hardware. Speed increases of up to 100% are not uncommon, and your hardware suffers much less wear and tear!

O&O Defrag includes a clever scheduling function, which allows you to schedule regular automated defragmentations if you wish. In addition, the permanent and automatic optimization in the background is key to prevent a loss in performance of your computer as well as a renewed fragmentation. This will allow you to save time compared to running a manual defragmentation.

O&O Defrag also features a built-in O&O DiskStat that offers a quick overview of how the hard drive is used. Users can easily search for files or folders that are taking up valuable disk space on the hard drive and slowing down your system. This versatile tool offers a Windows - Explorer type intuitive interface and a variety of options to hunt for space wasters.

O&O Defrag uses 100% Microsoft Windows API’s to move and rearrange data and files. Thus performing defragmentation processes with the software is as safe as running the Windows system itself and for example moving a file with the Windows explorer.

O&O Defrag is offered in three editions (Compare Features):
