The Miscellaneous branch under Configuration - Display - Folder has the following options:
Show preview file
If this option is selected, an additional pane is displayed to the right during a folder compare and when files are selected in the Folder Mode output that only occur on one of the compared drives or where files are identical, their content will be displayed in the additional pane for faster review of compared differences between folders.
Enable Stripes
If this option is selected alternating background colors will be used for lines in Folder compares.
Show file/folder icons
If this option is selected, the same icons used by Windows Explorer will be displayed before the file/folder name during folder mode compares.
Display root directories
If this option is selected, the full directory tree will be displayed from the root when a folder compare is executed. If this is not selected, the folder compare will only display the directory tree beginning with the folders being compared.
