O&O Defrag - 28
ClusterView
The display will show a certain amount of clusters arranged graphically as a block. The number of clusters per block is
indicated in the title line of the Cluster View. You can change the size of the blocks and the way they appear on screen.
This can be done using the right-click menu. The Shaded View will display the actual used space of a block in a mixed
color. If you choose not to use shading, the block will be displayed in prioritized full color. The varying conditions that
can be prioritized with color are listed in the chart below.
