Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. O&O Defrag 22 Professional puts is a replacement for the standard Windows defragmenter, that offers a much advanced set of features. It puts fragmented files together and maximizes your system speed and offers five different defragmentation strategies, as well as OneButtonDefrag technology for automatic adjustment of the settings best fitting for your system.
NEW! O&O Defrag 21 Professional - Make Old PCs Run Like New Again!
Fact: If you’re using traditional hard disks, they will slow down. It may take a while, you may not have a dramatic crash, but it will happen for sure. But not to worry…
The all-new version of O&O Defrag is here – O&O Defrag 21 Pro! Whenever it saves data, Windows scatters file fragments all over the hard disk and this slows down access times considerably. O&O Defrag lets you merge the individual fragments so that files are then positioned consecutively on the hard disk. The result is faster system starts and accelerated programs.
Increase performance, decrease costs!
PCs get slower in the course of their use. Two of the main reasons are the fragmentation of files and the storage of superfluous files. The new O&O Defrag 21 addresses these problems and ensures a significant speed increase and more comfortable work on the PC. A life expectancy for a PC of three to five years is no longer a rarity, especially since by Windows 10 many older PCs with a modern operating system can be used even longer. However, this also results in a significant loss of performance in the long run, since the continuous storage and deletion of files dramatically increases the fragmentation, resulting in noticeably longer access times during loading. The same applies to the temporary files created by many applications, which slow but surely “fill” the system and thus also reduce the speed during the daily work on the PC. Let O&O Defrag 21 Pro optimize your hard disks and SSDs, and you will get more speed while saving money on your hardware.
NEW: O&O DiskStat 3
For this purpose, the defragmentation algorithms have been improved with a view to saving the system resources and a better strategy when placing the files for even faster file access. In addition, O&O DiskStat is available free of charge for O&O Defrag users as a standalone application for finding and removing large and unnecessary files, in order to be able to clean up with a few clicks in case of storage shortage.
Optimized: Disk Cleaning
As requested by many customers, the O&O DiskCleaner function has been optimized once again in O&O Defrag and now allows for the automatic deletion of superfluous files in combination with a subsequent defragmentation for the maximum gain in performance.
Don’t miss out on the many new functions in O&O Defrag 21 Pro! Grab your copy now in our Online Shop, or alternatively test it for 30 days now on your current Windows system – free of charge and obligation. As well as the new functions, the old and trusted features for speeding up your PC and extending the lifespan of your hardware are all there too.
Here’s what some happy customers are saying about O&O Defrag:
“We have been using O&O Defrag now for many years and are very satisfied, not just with the software but also the support we receive.”
Ralf Linka, Horváth & Partners
“Only O&O Defrag Server is able to defrag these enormous, sometimes 400 GB files. All other products we tried simply couldn‘t do it.”
Scott Brown, SMI.
Defragment your system regularly!
Only defragmentation on a regular basis can ensure that you always get the best out of your system! For this, O&O Defrag offers you automated optimization and several options for scheduling a defragmentation
Recommended use defragmentation plan

For constantly running gaming computers we recommend manual defragmentation. Only the gamer himself can decide when he can afford to lose system performance as a result of defragmentation. Alternatively, we recommend configuring the O&O ActivityMonitor so that an automatic optimization will not start while a game is running.
For a regular desktop PC, where mainly Internet or office applications are used, or even some games are played, we recommend keeping the default setup of O&O Defrag. Automatic optimization makes sure that your system is always running at its optimal performance level – without any effort on your part.
For office computers requiring average performance, the rule for for private desktop PCs should apply: We recommend keeping the default setup of O&O Defrag as it is.
With video editing or hard disk recording systems the data throughput of the disk subsystem plays a decisive role. In particular with hard disk recording systems, some unwanted failures might occur which can render an entire recording session useless. We recommend manual defragmentation of drives before and after a session. Please do not use automatic optimization. It could start analyzing your drives while you are working!
For Servers used heavily during the week or in daytime, we recommend a nightly job which runs an Optimize/Quick as well as a complete Optimize on the weekend.
Don’t wait too long before you defragment!
As soon as you’ve installed your operating system, the file system will begin to fragment. Avoid reduced performance right from the beginning and install O&O Defrag as quickly as possible! Only then can you be sure that your hard disks will access your files quickly. You will also avoid unnecessary wear and tear on your hardware due to increased movement of the read/write head.
Avoid moving large numbers of files during defragmentation
O&O Defrag will calculate the best position for your files before and during the defragmentation. If you copy, move or delete files, these calculations will have to be carried out again. This will take time and lengthen the defragmentation time.
Automatic defragmentation with the threshold tool
Besides the default automated optimization in the background, O&O Defrag offers you the possibility to run job based defragmentation at fixed times. You can shorten the duration of a defragmentation by specifying a border value for its execution. This means that defragmentation will only take place when a particular degree of fragmentation is reached. You can thereby avoid unnecessary defragmentation runs. In the job dialogue under Drives, just enter a degree of fragmentation, e.g., 5%, upon which the job should be run.
O&O Defrag on notebooks
The Power Management enables you to prevent defragmentation if your notebook is running on battery power. The length of your battery’s life will therefore not be affected and you won’t have to stop the defragmentation manually. O&O Defrag recognizes the switch between main and battery power and will run the defragmentation according to your own configuration. You can read more about this in the section Settings.

O Come All Ye Faithful Lyrics
Particularly in the case of workstations or servers that are under pressure all the time, it is important that defragmentation take place in the background without negatively affecting the day-to-day running of the system. In such situations, we recommend you use O&O ActivityMonitor for keeping an eye on the resource usage and automatically adjusting the burden placed on your system by O&O Defrag.
O&O Defrag and Firewalls
At the start of O&O Defrag, my firewall notifies me of an attempted access. I receive the error '10061'. Why does this happen and and how can I solve the problem?
The communication of the individual O&O Defrag program components (O&O Defrag Agent and user interface) is based on TCP/IP. This communication only runs inside your computer - without any access to the Internet or the network. Most firewalls, however, are programmed to recognize internal IP communication, so you receive a warning message.
You don't have to turn off your firewall! Simply open up port 50300. Since O&O Defrag automatically checks access permissions, there can be no external access over this port even if you are connected to the internet.
In most cases, it is enough to authorize O&O Defrag for exclusively internal communication when the software is started for the first time.
If this did not happen, however, including the files OODAG.EXE and OODCNT.EXE on your firewall’s list of trusted programs has also proven successful with all of the firewalls we have tested.

Does optimization of SSD drives function in a RAID array?
O&o Defrag 21 Professional
No. RAID controllers are presented as a virtual drive to the operating system. The actual drives are hidden and cannot be approached technically.
