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! O&O Defrag Professional Edition is a powerful tool used for defragmenting partitions, thus optimizing your computer's performance.

Shadow Copy is a feature that automatically creates copies of files that are currently being used, at regular time intervals. It can be either enabled or disabled.

Disk defragmentation can be performed in several ways - Stealth (faster and uses little memory), Space (consolidates data, and further fragmentation is prevented), Complete / Name, Complete / Modified, or Complete / Access (these three methods also reorganize file structure in alphabetical order, or according to the last time when they were modified or accessed). O&O Defrag Professional Edition can also adapt itself to system load (thanks to the O&O Activity Guard), create a before and after report, use power management for notebooks, defrag when the screensaver is running, defrag multiple drives simultaneously or individual files and directories, and more.

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.
