Berlin, Germany, based O&O Software GmbH has been
developing tools for Windows since 1997. These tools
have been used in more than 140 countries around the
globe. We always make every effort to provide the right
tool at the right price. The numerous awards and prizes
we have received confi rm that we are on the right track.
Our most widely known product is O&O Defrag, a defragmentation
software for Windows that has set the
technical standard time and time again. Our commitment
towards continual advancement of our existing products
and introduction of new products guarantees the protection
of our customers‘ investment and that they will receive
the optimal value.
The new O&O Defrag 22
Our new O&O Defrag 22 Pro is now available and brings
groundbreaking new features!
Our O&O research department has developed a groundbreaking new
defragmentation method: SOLID. The new SOLID method from O&O
Software is the most resource and hardware-friendly
defragmentation method and
prolongs the lifespan of both conventional hard disks and SSDs.
SSDs store file fragments spread across many blocks, even though
much fewer would suffice. This memory behavior has an immediate
effect on the performance and lifespan of an SSD. To counteract
wear and at the same time to optimize the performance of SSDs,
O&O Software has developed the new defragmentation method SOLID.
By using the defragmentation method SOLID, these distributed
file parts are defragmented so that in the future significantly
fewer memory cells have to be read out and also written to when
changing a file. As a result, the SSD is faster as the number of
read and write accesses is reduced by the defragmentation. In
addition, the premature wear of the SSD (and of course the
conventional hard drive) is prevented because fewer blocks need
to be erased and rewritten than before the defragmentation with
A positive side-effect of developing the defragmentation method
SOLID has been found in tests on “classic” hard disks: it is O&O
Defrag’s most resource and hardware-friendly defragmentation
method ever, with optimal results, and sets the new standard for

with the new SOLID method!
The new O&O Defrag 22 not only defragments traditional
hard disks but also SSDs. As a result, the SSD is faster as the
number of read and write accesses is reduced by the
defragmentation. In addition, the premature wear of the SSD (and
of course the conventional hard drive) is prevented because
fewer blocks need to be erased and rewritten than before the
defragmentation with SOLID.
Did you know,
that defragmenting your hard disk(s) provides the largest
performance gain possible for a PC - even in 2018 (aside from
hardware upgrades)? The gains in speed from using O&O Defrag 22
are all the more noticeable the more intensely a computer is
used or when the last defragmentation was made a long time ago.
Did you know,
that a regular defragmentation not only speeds up your computer,
but also reduces wear and tear on your hard drives and - new!-
Let O&O Defrag 22 Pro optimize your hard disks and SSDs, and you
will get more speed while at the same time saving money on your
New: O&O Defrag 22 - Optimize Hard Disks And SSDs
O&O Defrag 22: Functions
Up to 100% increased PC speed: There is nothing worse than when you want to do something on your PC and your computer is running slow. A disk defragmenter used regularly can speed up a PC of any age and get it working like new again!
Don’t let a slow computer spoil your work or fun! Let O&O Defrag optimize your hard disks and – New! – SSDs and you can experience speed increases of up to 100%! Regular disk defragmentation optimizes your PC performance!
When you defragment, the files that Windows splits up when saving documents across the hard disk or SSD are put back in order again so that files can be quickly recognized and found by the SSD or the read and write heads inside your HDD. Speed increases of up to 100% are not uncommon, and your hardware suffers much less wear and tear!

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.
O&O DiskStat enables you to analyze used space on your hard disk with the help of Charts (Pie chart or Bar graph). As soon as you start the program, you are presented with a concise overview of your entire hard disk. With the help of O&O DiskStat, you can identify and dispose of superfluous files, saving yourself valuable hard disk space in the process!
The brand new in-built O&O DiskCleaner searches for and removes temporary and unnecessary files that are taking up memory and increasing fragmentation. O&O DiskCleaner also increases the security of your data, as private content (e.g. Thumbs.db, copies of documents, drafts of emails, Dumps) will no longer be kept as copies in unnecessary system files.
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 can be configured with just three clicks and optimizes your disks behind the scenes with no negative impact on your 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.
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
