## Files in Directory Tree

### Do not show single files in the Directory Tree

### Show single files in directory tree

If this option is activated, the directory tree will list single files.

## Gradient Bars

### Show gradient bars as size indicators in directory tree

If this option is active, a gradient bar is shown in the background of every folder in the directory tree that indicates the size of the folder in relation to the entire scanned file system tree. Use the color picker below to define a custom color gradient.

## Tooltip

### Only for cut off labels

### Show long tooltips in directory tree

If this option is active, a tooltip window with detailed information will be shown if the mouse cursor hovers over a folder for a while. This is useful if you want to take a look at detailed information of a folder without switching to the “Details” view,

### Show a preview of the hovered folder’s contents

Allows you to peek into a folder without actually expanding the folder in the directory tree.
