With fully automatic defragmentation for the home user, professional settings for power users and application across company networks, O&O Defrag ensures sustainable and maximum speed for any computer. At the same time, a regular defragmentation protects the mechanical parts of a PC and extends the lifespan of the hardware. That a defragmentation can help rescue data in an emergency would not occur to most users. However, in the event of a loss of data, the chances of a successful rescue of that data are greatly increased when a defragmentation has been carried out, as data recovery programs can reconstruct intact and whole files much easier than files that are spread in fragments across the disk.

During the defragmentation process, a dynamic block view is displayed, and with help from a before-and-after view, the user can clearly see how much their system is being optimized. Using detailed statistics, O&O Defrag displays how many fragmented files were corrected and how many files were accelerated as a result. Users can therefore see what effect regular defragmentation has on their system performance, can track the success over weeks or months and better adjust the program settings to suit their individual needs.
