Slow compared with Perfect Disc 12. A lot slower.

My favourite of the 3 I have (O&O Defrag Pro, Diskeeper Pro, & PerfectDisk).

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.

An outstanding defragger, but for the bugs. I kept having problems with the service not talking to the GUI, or even losing its brains completely, doing nothing.

Poor kids and cheapskates always slam commercial software in favor of half-baked freeware, but it makes no difference.

O&O Defrag doesn't "open online connections" for nefarious purposes. The defrag service talks to the GUI by way of a TCP port. This is a common practice for software that combines a background service with a front-end GUI. It's also mentioned in the help file.

O&O Defrag doesn't slow anything down. In fact, if you enable "AutoSense", it stays out of your face and does its thing without driving you nuts. Compare that to freeware crap that not only requires you to run it manually, but slows your system to a crawl while it runs.

Slow, extremely dumb, and system respons actually worse than a fragmented drive.

Whatever 'shareware' defragmentation software you choose, unbiassed reviewer ALL show that they actually slow the performance down. Don't fall for their lies and marketing talks.

Nothing but marketing releases since version 8.5

Now that ultradefrag has boot time, O&O is no longer relevant.

O&O Defrag does a good job but in my opinion not a great one. I used it for around 2 years then moved over to PerfectDisk which to me is the best around.
Still for anyone who hasn't tried anything beyond Windows built in defrag utility it is a massive improvement.
I do like the right click on a block to see the contents which is a nice feature.
Another defrag app worth trying is Puran Defrag which is lightning fast and does a great job.

Getting back on topic though O&O Defrag kicks Diskeepers butt all over the place and I reckon if I had to name my top 3 defraggers it would be.

1 PerfectDisk
2 Puran Defrag
3 O&O

This is the only program that gives me 100% defragmentation on my HD, I use also Perfectdisk that is better in giving more continuos free space, but isn't that good in defragmenting.
I had the same issue of the user above, with O&O freezing on a file and using 100% CPU usage. I solved the issue running SPINRITE 6 on the drive, so it was a problem of the surface that even chkdsk with surface scanning didn't notice.
In that case Perfectdisk gave me no issue at all, maybe it's smarter and skips difficult files or sector (thus leaving more defragmented files).
O&O defrag lacks of an error.log, that would be useful.
The issue I had could have been solved easily skipping the file and letting me know the program had a problem writing on a specified sector.

Except for individual file/directory defragmentation on demand, there are no new useful feature since its 8.x version. Unfortunately, its defragmentation on demand feature is just a workaround feature rather than part of the main defragmentation feature. Other new features are just cosmetics, shortcuts, wizards and monitors which are useless.
