The following is a comparison of notable file system defragmentation software:ġ0.2.0.1 (Free), 4.11.0.7 (Ultimate) (January 26, 2022 ( ) (Free), March 3, 2020 ( ) (Ultimate)) ĭrive Optimizer (formerly Disk Defragmenter) ( August 2022) ( Learn how and when to remove this template message) Several templates and tools are available to assist in formatting, such as Reflinks ( documentation), reFill ( documentation) and Citation bot ( documentation). Please consider converting them to full citations to ensure the article remains verifiable and maintains a consistent citation style. Allmethods can be applied to any drive – including storage space, volume and stripe sets – and ofcourse ensure maximum resiliency.This article uses bare URLs, which are uninformative and vulnerable to link rot. The best possible utilization of the available storage space also prevents renewed fragmentation. Even a change from hard disk to SSD will be recognized and the optimization strategy adjusted accordingly. And as always, everything happens automatically in the background. After defragmentation, the SSD works faster and its lifespan is extended because fewer read and write accesses are needed. This results in read and write processes requiring fewer accesses to these memory cells in the future. Thanks to the SOLID/COMPLETE method, data fragments scattered on SSDs will be combined and saved in fewer memory cells. They require more time and memory for this. STEALTH and SPACE are optimized to perform the defragmentation as quickly as possible, while the COMPLETE methods additionally achieve a complete rearrangement of the files.

The defragmentation methods STEALTH, SPACE and COMPLETE have been optimized again. The extensive classic interface is retained for the previous professional users. The newly released O&O Defrag 26 offers a new and modern interface that makes it very easy, especially for PC beginners, to carry out the important optimization measures. In addition to the defragmentation, not only is a disk cleanup function now available but also the deletion of unnecessary Windows and desktop applications as well as a helpful check and repair of Windows. With O&O Defrag 26, Berlin-based O&O Software GmbH is releasing a completely revised version of its popular optimization application.
