In the long run, any computer becomes slow, as files are stored as tiny pieces and scattered all over your hard drive or SSD. O&O Defrag Professional & Server corrects this by rejoining these pieces of the file and rearranging them in a faster manner. This leads to improved startup times, smoother operation and an increased life of your storage hardware.

One does not have to be a technology expert to use O&O Defrag. The interface is easily optimized and automatic, yet the more experienced users can enter a professional environment with the classic interface. You may leave it to run in the background, or you may initiate a defragmentation process with a single click- either way, your system is kept in a clean state without trouble.

O&O Defrag Professional & Server is provided with clever new options such as O&O Visual Disk to display SSD write activity, O&O StartupManager to reduce unwanted programs at startup, and Boot-Time Optimization to prepare system files before Windows is loaded. It will also clean the junk files, identify errors, and even support the latest ARM-based Windows devices so your PC or server can always perform optimally.
