O&O Defrag Professional Edition22.1 Build 2521

O&O Defrag Professional Edition is a powerful tool used for defragmenting partitions, thus optimizing your computer's performance.The user interface is easy to follow. It has a ribbon bar that displays all possible actions made in O&O, a list of available local drives, and a few tabs: cluster view, history of fragmentation, drive status, jobs, reports, and file status.The cluster view displays the amount of clusters arranged graphically as a block. The blocks are shown in prioritized colors - free, compressed, allocated, fragmented, reserved for MFT, system, paging file, locked exclusively, being processed, and folders.Shadow Copy is a feature that automatically creates copies of files that are currently being used, at regular time intervals. It can be either enabled or disabled.Disk defragmentation can be performed in several ways - Stealth (faster and uses little memory), Space (consolidates data, and further fragmentation is prevented), Complete / Name, Complete / Modified, or Complete / Access (these three methods also reorganize file structure in alphabetical order, or according to the last time when they were modified or accessed).Furthermore, it is possible to schedule a defragmentation (once, or at a regular time interval), so it automatically performs.O&O Defrag Professional Edition can also adapt itself to system load (thanks to the O&O Activity Guard), create a before and after report, use power management for notebooks, defrag when the screensaver is running, defrag multiple drives simultaneously or individual files and directories, and more.Our tests were run on a heavily fragmented partition of 250GB, and O&O did a good job, but not extraordinary. Space could have been further optimized.CPU and memory are either moderately or highly demanded (according to the type of defragmentation) when O&O is performing a task.All in all, O&O Defrag Professional Edition is a great piece of software for defragmentation purposes. It improves the boot time and the overall performance of your computer.
