Start64!Fragmentation can cause your computer to slow down drastically. When saving data, the operating system scatters it all over the hard disk and this slows down the time needed for accessing files. To make sure you have the fastest access times possible, keep the data on your disks arranged in perfect order.

O&O Defrag merges the individual fragments from files and then sorts all data into separate zones. To accomplish this, O&O Defrag gives you three new methods of defragmentation that combine perfectly with all its standard options. Altogether, they allow you to customize the way files are organized on your computer.Your system will start faster, running programs will be speeded up, and new fragmentation can be avoided!

Optimizing Solid State Drives (SSDs)

For the first time, O&O Defrag enables you to optimize all makes of SSD drives. Using regularly scheduled ATA TRIM commands, an SSD will be kept informed of those hard disk areas that are available for new data. Instead of continuing to save the contents of data that’s no longer needed, the SSD can now use those freed areas for a drive-internal optimization of its data management. As a result, the SSD is able to process accesses significantly faster, and wear out on flash chips is kept to a minimum.
