A powerful tool used for defragmentation
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.
Defragmenting your PC can hugely accelerate the speed you can work on your PC. 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.
