deskfolders.dll is the only one i have found to be reliable, i.e no crashing etc. on 9x or NT/2k/XP. i don't recall if ndi had stability issues, but iirc it's not as useable as deskfolders.

deskfolders's in simplicity - and it's on by default too, with room for eight icons to be shown on the desktop. if you need more than eight, edit the deskfolders section of config\base.rc

the icons that will be displayed on the desktop (in simplicity, other themes may vary :|) are in yourLiteStepDir\shortcuts.

hope that helps. :P
