New functions in version 12
All your system's files will be sorted by O&O Defrag 12 according to their level of use, and each one will be separated into its own section of the hard disk. Thanks to the division into drive zones, all files are rearranged optimally after the defragmentation. O&O Defrag 12 introduces 3 new defragmentation methods, which work perfectly in combination with the previous methods. All of this will allow you to start your computer and its programs faster than before, and actually prevent any sudden increase in fragmentation. In addition, subsequent defragmentations will run much faster. Zone filing can also be supplemented by a user defined file organization.

Creation and consequence of fragmented files
Fragmentation can drastically slow your computer down. When saved by the operating system, files are broken into fragments and dispersed across the entire hard disk. Increased fragmentation ends up having an extremely negative effect on your access times. O&O Defrag is the perfect remedy. A defragmentation rearranges the individual data fragments and writes them contiguously on the hard disk. This is really the only way for your computer to regain its original power and performance.

Drive zones
The data is inspected according to set criteria, and then filed into separate zones on the hard disk. A special algorithm organizes the data optimally onto the disk following the defragmentation. System files which have to be accessed quickly, for example, will be separated from the rest. Between the zones there is free space so that new files can be immediately moved to the correct zone. This logical organization considerably reduces the time needed for future fragmentation, and also prevents new fragmentation from occurring in the first place.

Automatic defragmentation run
The O&O-OneClickDefrag wizard makes it easier to select the optimal strategy for automatic defragmentation. Depending on how you use your computer, whether for gaming or for work, O&O Defrag configures different strategies and combinations for automatic defragmentation, and over time, even adapts to new circumstances. In addition, you can set O&O Defrag to start the defragmentation whenever a certain.
