Disable autolisting of subfolders for a rootfolder

I only want to display some of the subfolders, not all.

So is there a way to disable the autolisting of the subfolders.
I'm adding the subfolders that i would like to see by AddSubFolder() method

Youcan mark the subfolders in question hidden in Windows Explorer and then set ShowHiddenFilesAndFolders property to false. This way the subfolders will not be displayed.
