O&O Defrag gives you everything from fully automated defragmentation to a professional set up: everything a good defragmentation software should give you.
An increasingly fragmented hard disk compromises the performance of your computer. This occurs as a result of frequent write and read access, during your daily routines, while surfing or gaming, or due to frequent user access on Server. For a lasting maximum speed while accessing files, it is important that your data is organized systematically.

System Requirements

If you spend a lot of time on your PC, slow system and program starts or system crashes while playing can be very frustrating. Periodic defragmentation often works wonders in bringing new life to a PC.

Your privacy is our priority

Our latest version of O&O Defrag can also be used for deleting free space on hard disks. This prevents traces of confidential data left over from partially-deleted or temporary files from falling into the hands of any strangers.

Benefits of a clearly laid out hard disk

Whenever it saves data, Windows scatters file fragments all over the hard disk and this slows down access times considerably. Defragmentation reverses this by rearranging data and speeding up access times dramatically. This not only saves the user time, it also reduces wear on hard disks and extends their life expectancy. Defragmentation can even make the difference if you lose important data because chances of full recovery are better on a defragmented disk. Why? After defragmentation, it’s easier for data recovery software such as  O&O DiskRecovery to restore files when they’re not scattered across multiple areas of a hard disk.

Automatic background defragmentation

Automatic defragmentation is enabled by default following installation and optimizes disks behind the scenes, without interfering in a computer’s performance. You can set O&O Defrag to run defragmentation at a certain level of fragmentation, on particular days of the week, or whenever your screensaver is being used. Defragmentation can be paused and resumed whenever you want because O&O Defrag automatically recognizes where defragmentation was interrupted.

Recommended use

We recommend manual defragmentation for PCs that are being used heavily because only a user can decide when the time is right to give up the performance needed for running defragmentation. On computers using video editing or graphics applications, O&O Defrag can be configured to not start automatic optimization while certain programs are running. The default settings in O&O Defrag are more than adequate for ordinary desktop PCs running mainly internet or office applications. O&O Defrag is also perfect for notebooks. Whenever an external power supply is disconnected, O&O Defrag automatically goes into pause mode to save energy.
