O&O Defrag 26 Professional Edition Review at a Glance
Use O&O Defrag when you need to encourage a slowing down computer, which can be caused by slow data loading from the hard disk. O&O Defrag analyzes your computer’s hard drive up to three times faster than the standard data defragmentation features built into Windows.
O&O Defrag 26 Professional Edition activates the hidden performance of your computer and packs file fragments efficiently and securely together. This professional defragment software gives you everything from fully automated defragmentation to a professional set up: everything a good defragmentation software should give you.

An increasingly fragmented hard disk compromises the performance of your computer. This occurs as a result of frequent write and read access, during your daily routines, while surfing or gaming, or due to frequent user access on Server. For a lasting maximum speed, while accessing files, your data must be organized systematically.
Windows disperses single file fragments all over the entire hard disk, which increases the time for its access. The defragmentation packs file fragments coherently together on the hard disk and file the data into separate zones. Windows, as well as other programs, will start and run faster.
O&O Defrag 26 Professional Edition includes a clever scheduling function, which allows you to schedule regularly automated defragmentation if you wish. Besides, the permanent and automatic optimization in the background is key to prevent a loss in the performance of your computer as well as a renewed fragmentation. This will allow you to save time compared to running manual defragmentation.

O&O Defrag 26 Pro goes to work with its SOLID/COMPLETE method. Scattered file fragments will be reconnected and saved in fewer memory cells. This leads to fewer read and writes accesses to these memory cells. The result is the SSD runs faster and its life expectancy increased on account of reduced read and write accesses.
Along with the new SOLID/COMPLETE, the existing SOLID/QUICK method has been extended: it is now faster than COMPLETE and suitable for occasional faster defragmentation:
- SOLID/COMPLETE: This method, developed specifically for SSDs, is a thorough optimization of the SSD.
- SOLID/QUICK: This method, developed specifically for SSDs, performs a superficial optimization of the SSD. This method is gentler and faster.
- ClusterView for SSDs: To represent the degree of fragmentation of an SSD, the ClusterView now maps the logical structure of an SSD so that, accordingly, 6 blocks are combined into one.
Both methods sustainably extend the life of the SSD but differ in terms of the duration and protection of the hardware.

The Problem: Every file system is fragmented. This means that over time, files will no longer be filed consecutively but, instead, be scattered across the computer’s entire storage area, slowing down access to these files. This problem doesn’t just apply to hard disks but to SSDs as well. Over the course of time SSDs save file fragments over more memory cells than are necessary. This, in turn, leads to a continuous slowing down of the read and write processes, just as we experience on hard disks.
The Solution: This is where O&O Defrag 26 goes to work with its new Install & That’s All feature. O&O Defrag 26 will configure and run all settings automatically, according to the specific requirements of your system. Scattered file fragments will be reconnected and saved in fewer memory cells. This leads to fewer read and write accesses to these memory cells. The result is the hard disk and SSD running faster and their life expectancy increased on account of reduced read and write accesses.
With O&O Defrag 26, we present our “Install & That’s All” function, a world first! Especially now, with many of us working from home, the reliable and optimal performance of our PCs is more important than ever. Time is also of the essence. That is why we have developed “Install & That’s All”. All you have to do is install the program and O&O Defrag 26 does the rest, fully automatic, in the background and with no impact on your system. It saves you the time and stress of configuration, letting you focus on the important things.

In O&O Defrag 26 the S.M.A.R.T. functionality has been integrated that indicates the “health status” of hard disks, SSDs, and RAIDs whenever there is any problem. Such a problem could be a high temperature, or an error reported by the drive itself. If there is anything unusual going on, a message will be displayed in the Windows Action Center. This functionality notifies users of any problems and gives early warning about any impending crash of a disk.

The read and write accesses on the computer will be more visible. Users can see the read and write operations currently being run on any drive displayed in the taskbar. A search on the respective drive can be started by right-clicking.
O&O AppBuster

In a clear display, O&O AppBuster shows which apps are installed on the computer – even hidden apps are also displayed. O&O AppBuster makes it possible to remove unwanted apps quickly and easily. Or, if one of these apps was accidentally uninstalled, it can be restored with one click.
Modern Interface

The modern interface offers compact access to all important functions as well as additional components. For example, the operating system can be checked for inconsistencies, the installed apps can be displayed, or temporary and superfluous files can be deleted.
The main reason is the disorderly, inefficient storage of files on hard drives and SSDs. The new O&O Defrag 26 fixes this problem for you. It speeds up your computer, prolongs its lifespan and makes your PC work better.
What’s New
We are proud to introduce to you today the new version 24 of our award-winning speed-up product, O&O Defrag, with a unique “Install & That’s All” feature! O&O Defrag makes PCs of any age perform like new again – you can experience speed increases of up to 100%!

The main novelty of the current version of O&O Defrag Pro is an improved way of defragmenting SSDs, which prevail in newer computers. This method consists in defragmenting only those memory cells for which it is really necessary to move the data. As a result, O&O Defrag optimizes data loading without excessive wear on the SSD. This specialized program will also find more fragmented blocks of data. Additionally, if you have multiple physical hard disks in your computer, O&O Defrag Professional optimizes their contents in parallel mode, which significantly and shortens the total time required to defragment data.
The other functional equipment of the program is also rich: in addition to various defragmentation methods (continuously in the background of the operating system, when the computer is idle or at selected times) O&O Defrag PRO also includes tools for optimizing SSDs and a function for thoroughly erasing disk space to avoid possible to restore old files. You can also set up a quick optimization of the contents of the disk every time you start your computer – before Windows starts.
When the computer is idle or at a selected time), O&O Defrag also includes tools for optimizing SSDs and a function for thoroughly erasing disk space so that old files cannot be recovered. You can also set up a quick optimization of the contents of the disk every time you start your computer – before Windows starts.
Use O&O DiskCleaner to remove unnecessary temporary files from your disk to free up space while reducing disk fragmentation. It has his own tab in the ribbon. The first step is to perform the analysis: On the »O&O DiskCleaner« tab, select the disk you want to analyze and use the »Analysis« button.

When the analysis is complete, the program displays the results at the bottom of the window. If you decide to clean the disc, use the »Cleanup« button. The cleaning process is displayed in numerical values and can be paused or terminated prematurely with the »Pause« and »Stop« buttons.
