Each plugin can have an icon in Network Neighborhood to the left of its name. Totalcmd will load the FIRST icon it can find (by index) in the plugin DLL, so just include a resource file with exactly one icon in it. The icon should contain at least one image with 16x16 pixels, although larger images will be scaled down for displaying in Totalcmd. If no icon is contained within the plugin DLL, Totalcmd will show the default folder icon.

 

The icons in subfolders will be determined with the normal file association process in Windows.
