O&O Defrag Professional Edition 17.0 Build 504


O&O Defrag Professional Edition has a nice user interface which is built based on ribbon-style menus. There are large icons with decent descriptions which is very important for every user to quickly find every function. All available hard discs and their partitions will be listed in the upper half of the program screen. The lower half has seven tabs located at the very bottom of the screen, which are: Cluster View, Time View, History, Drive Status, Jobs, Reports and File Status. Switching between them will show you the corresponding information in the lower part of your screen.

Basic Operations

To work with O&O Defrag Professional Edition 17.0 is very easy and every beginner or advanced user will not face any problems in order to use it. The Options menu is where you have to click if you want to enable all available drives to be analyzed, the free space to be wiped out or thin provisioning optimization to be performed.


To sum things up, O&O Defrag Professional Edition can create detailed reports about everything you want. It heavily uses your system resources so you better leave it alone until it is over. Another way to use it is if you create a schedule for the defragmentation procedure, which will coincide with your lunch break or non-working hours.
