Cross file system boundaries (only NT and higher). Under NTFS volumes can be mounted in directories. By default WinDirStat stops reading at these mount points, i.e. it shows only the usage of one file system. Here you can change this behavior. (No mount points are recognized on UNC drives.)
Follow Junction Points (except Volume Mount Points) (only NT and higher). Under NTFS target folders can be grafted onto another folder by using junction points. (You need a third-party tool, e.g. awxlink, downloadable from http://www.arniworld.de/, to create junction points.) By default WinDirStat stops reading at these junction points. Here you can change this behavior.
List Style. These options, grid and stripes, apply to all lists in WinDirStat.
Language. In addition to the built-in language English, this combo box offers those languages, for which a correspondig wdsrxxxx.dll exists. The setting takes effect next time when WinDirStat is started.
Two options which control what the columns 'Subtree Percentage' and 'Percentage' display during the scan. Colors for the subtree percentage presentation.
Squarification style, parameters for the cushion shading, grid lines, color of the selection rectangle.
