The new O&O Defrag 31 now includes new, unique features to keep your PC running like new.

The number one cause of slow PCs

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: O&O Defrag 31 takes system optimization to another level. You can simply install the program and let it do its work. It will intelligently carry out whatever is needed on your PC on its own. O&O Defrag 31 will configure and run all settings automatically, according to the specific requirements of your system. Maximum performance practically out of the can.

New: A significantly optimized engine

We have significantly optimized the underlying engine, resulting in noticeably faster performance. This means quicker processes, improved efficiency, and an overall more responsive experience.

New: A completely redesigned user interface

We have introduced a completely redesigned user interface that offers a modern look and a more intuitive user experience. Every element has been carefully crafted to improve usability and make navigation smoother than ever.
