Do not wait too long! If you work on computers a lot, then slow system and program starts, endless rendering and memory processes, or even system crashes when playing can quickly ruin your enjoyment. Defragmenting your PC can hugely accelerate the speed you can work on your PC. When you defragment, those files fragmented across the hard disk are logically rearranged so that files can be quickly recognized and processed by the hardware. Performance gains of up to 100% are not uncommon!

In the new version of O&O Defrag, you can now see what the program does for your system thanks to graphics and statistics, which give you a before-and-after Defrag contrast!

Privacy in capital letters: O&O Defrag 17 can also be used for deleting free space on hard disks. This prevents traces of confidential data left over from partially-deleted or temporary files from falling into the hands of any strangers. Simply let O&O Defrag 17 Pro confidential data securely automatically after a defragmentation run.

With O&O Defrag 17, several drives can be defragmented simultaneously. In addition, the algorithms have been substantially accelerated, reducing the time required for a defragmentation by up to 40%. By using O&O Defrag, files can be read and written much more quickly. What at first seems to be lost performance can easily be rediscovered and realized again with O&O Defrag, giving you the peace of mind that your hardware is in good health and operating optimally.

O&O Defrag works quietly in the background so that the defragmentation process does not disturb other tasks and has no negative performance impact on your systems.
