O&O Defrag Professional offers a multitude of different defrag options to suit all your needs, and does so in a clean and uncluttered environment.

Unlike other defrag software this title does not require you to stop applications in order to defrag, and there is no limit on the size of hard drives that can be defragged.

There are five different defrag methods on offer for all needs: Stealth, Space, Complete/Name, Complete/Modified, Complete/Access.

The Stealth is designed for use on PCs with large files and little free space, while the Space method is designed for heavily fragmented drives.

The three Complete methods (Name, Modified and Access) sort the files on your drives in different ways - alphabetically, according to date last changed, and according to date last accessed respectively.

The Name method is best for PCs where files are rarely changed, the Modified method for PCs where files rarely change, and Access method for most normal.

As an option, whenever your screensaver is activated, the defrag process will start. When you return to your PC, defragging pauses. Other expected features, such as scheduled defrags and report generation, are also included.
