    The best defrag app there is. Always has been. I've been using O&O Defrag since version 1.0 (Build 21) back in 1998. I've owned every version since.

    Today I'm running O&O Defrag 12, the most powerful version yet.

    Long live O&O Defrag!

    The best defragmentation application I've used!

    I've used this application for a few years now, while checking out other defrag apps at the same time, but none of them works as good as this one. I've tried PerfectDisk, Iobit Smart Defrag and Auslogics Disk Defrag, but the performance gain is always higher with O&O Defrag Pro. Quality German programming. (To any paranoid fileforum users: no I'm not affiliated at all to the O&O software company, nor am I paid by O&O to give this review.)

    Well done, developers. full score!

    I have used this software for quite sometime, present as well as previous versions and I can report that it works very well for me. I use it at home on my Vista computer thats used for gaming, and my work computer.
    I give it 5 stars becuase it works as advertised, and works well.
