NEW: O&O Defrag 31 Server Edition – Extend the lifespan of company Hardware

With O&O Defrag 31, you ensure maximum speed for your servers and extend their life expectancy.

Do you ever wonder why your systems get slower? Lagging performance on workstations and servers, slow start times…and maybe you wonder why you have to replace some hardware relatively quickly? It’s most likely due to fragmentation – Windows splitting up every file you and your coworkers and employees save into fragments, spread across the storage volumes.

Regular defragmentation of hard disk drives and solid-state drives in business servers and workstations enhances performance by ensuring efficient file organization, leading to faster access times and improved overall system performance. And due to less read/write actions, you can extend your company hardware life by up to 40%. This is of particular significance given the current rising costs of hardware.

NEW: Significantly optimized engine

In Version 31 we have significantly optimized the underlying engine, resulting in noticeably faster performance and greater stability. This means quicker processes, improved efficiency, and an overall more responsive experience.

NEW: Modernized User Interface

We have introduced a completely redesigned user interface in O&O Defrag 31 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. The new design is based on the current Windows style and provides a significantly clearer structure, faster orientation, and easier everyday use.

Also available over a Network Management Console

O&O Defrag can now be managed across a network. Roll out, install and manage the performance of your machines by deploying O&O Defrag over our RMM Software, O&O Syspectr. Over an intuitive dashboard with a whole range of monitoring and management functions, you can not only manage your system performance, but also be automatically notified of any issues. Any time, anywhere. All you need is an internet connection.
