I use a total of 17 partitions, and one thing I like about Defrag Pro, is that it allows me to forget all about defragging woes - by automatically defragging in the background whenever necessary. It's also possible to create jobs with a time schedule, which will only be run if and when a certain degree of fragmentation is reached (the threshold is a user selectable option). Also - very important for me - O&O employs a truly effective 'ActivityGuard' feature, which checks CPU usage during defragmentation and does a great job of ensuring that I can work undisturbed, whilst O&O Defrag works unnoticed in the background.

The program offers five different methods of defragmenting. You may find my logic a bit odd at first (?) but one method which I personally often favour (albeit for just some of my partitions) is to select to defragment using the complete/name method - which will sort files alphabetically from the beginning to the end of a partition.

An off-line defragmentation feature is also included, allowing locked system files to be defragmented on the next system start-up. But this isn't usually necessary as O&O Defrag 10 is able to defragment the registry databases and the MFT on Windows Vista/XP during a normal defragmentation process. An offline defragmentation for these files is not required.

There's also some very comprehensive records kept, and pretty HTML reports can be created.

There's a lot more on offer. I'm just skimming through the basics here. I must confess it's been quite a long time since I last had a very detailed look. But that's only because I've never had the need to! Unless I'm manually defragmenting a partition for some specific purpose, the set it and forget it strategy has worked wonders for me for years - and continues to do so.

I got banned on a board because I posted this on there :(.

Yes, this is a really good giveaway.

Its much better, more options, although I use perfectdisk v7. less bloated.
Saw this on 4 Free yesterday too.

What's the difference between this and the defrag function that comes on your computer?

Excellent software! I've been a registered user since version 4. The current version is O&O Defrag 12, but (in spite of tempting offers to upgrade) I've been happy to remain with O&O Defrag 10 which continues to meet my needs.

If this is a genuine 'no-strings' free license offer (as it does appear to be) then I fully endorse your recommendation. Grab it whilst available!

(one caveat - I don't think version 10 works with Windows 7)

If you have a 32 bit operating system use the 32-bit. I have a 64-bit vista and I had to use the 64-bit version. The 32-bit version wouldn't install. Install it and then after you install it enter your information that you received in the e-mail in the program. I had to restart the computer the program for it see it was a registered version. I restarted the computer because the icon was still seeing me as a trial user. But when I did that it showed I wasn't a trial user no more.

It may take a couple of minutes to receive the e-mail.
