Further information about O&O Defrag

Unleash the hidden performance of your computer with minimum effort. O&O Defrag 11 Pro packs file fragments quickly and securely back together to optimize your hard disk under Windows. The new background monitoring function helps to prevent fragmentation at the 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.

Fragmented hard drives slow down your PC!

Every time you write a letter, install a program, or save a file, the resulting fragmentation causes your computer to work just that much slower! In order to start a file or program, Windows has to first collect all the corresponding fragments that have been previously saved. It's a little bit like what happens after you've thrown all your socks into one big drawer and then, when you need a matching pair, have no choice but to scavenge through the colorful pile. Even the fastest processor is no great help the computer continues losing speed - speed that you once purchased with an expensive processor.

Not defragmenting ends up costing performance and money

O&O Defrag 11 Pro is able to restore your computer's lost performance. Safely and surely, it merges scattered data fragments and by doing so, optimizes the hard disk under Windows. Thanks to version 11's new background monitoring, this has been made even easier than ever before data that has been recently saved or edited will be analyzed and defragmented whenever your computer's full power is not being used. O&O Defrag makes sure, behind the scenes, that your hard disk is always performing at its peak.
