What is O&O Defrag?

O&O Defrag packs file fragments quickly and securely back together to optimize your hard disk under Windows. 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. Its functionality ranges from a fully automated defragmentation to an individual professional set up. It can do everything a truly good defragmentation software should be able to do. The new background monitoring function helps to prevent fragmentation at source. Newly added and modified files are analyzed and defragmented whenever they are not being accessed. O&O Defrag makes sure that your hard disk is constantly performing at its peak.
