O&O Defrag 17 Product manual

O&O Defrag 17 
Screen Saver

The O&O Screen saver will be automatically installed, if you don't de-select it explicitly during the user-defined installation.

Together with the O&O Screen Saver the defragmentation of the hard disk is started, while the computer is not in use.

The screen saver displays the defragmented drive in Cluster View so that you can follow the defragmentation live.

In addition, the status text generated by O&O Defrag is shown in the background.

As is the case with most screen savers, the operation of the O&O Defrag Screen Saver stops as soon as mouse or keyboard activity is detected.

Rotation Speed

This slide bar regulates the rotation speed of the defragmentation display.

FPS Limit

FPS stands for "Frames Per Second". This is the number of frames displayed on screen per second. A higher refresh rate means a higher hardware load, however it also means a better 3D display.

X, Y, and Z Position

These controls allow you to specify a horizontal and vertical positioning of the 3D view of a drive.

The control "Z-Position" changes the size of the 3D object.


If your graphic card supports edge smoothing, you will achieve a much better 3D illustration with this option.


Here you can select the drives that O&O Defrag Screen Saver should defragment. In the column "Action", select the desired method of defragmentation for the corresponding drive.

You can find more information about the O&O Defrag defragmentation methods in the chapter Select method of defragmentation.
