Schedule automated defragmentation

Optimize hard disks automatically

All modified and newly added files are checked during the automated defragmentation. Newly fragmented files will be automatically defragmented once they are no longer being accessed. This will ensure that your system is being constantly kept at its highest level of performance, and effectively prevent any additional fragmentation. The various zones of a drive will also be taken into consideration, when this option is enabled.

Optimize while the screen saver is running

The defragmentation always starts whenever your screen saver is on. For example, when you are out for lunch or away from your computer. Defragmentation will be cancelled whenever you’re working on your computer, and will continue once the screen saver comes on again.

Run defragmentation at a specified time

Here you can specify whether defragmentation should recur automatically. The next defragmentation will then start by itself without you’re having to start it manually.

Execute optimization of the system now

Optimize now

All your system's drives will be immediately defragmented. The system drive will be sorted using the OPTIMIZE/Complete method, all other drives will be consolidated using the OPTIMIZE method. We recommend this kind of optimization if you're using O&O Defrag for the very first time.

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.
