A powerful tool used for defragmentation
O&O Defrag x64 works quietly in the background so that the defragmentation process does not disturb other tasks and has no negative performance impact on your systems.
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!
