I agree that in a way, giving people more power might it easier to do more damage. That's why I suggest that the function not actually delete anything and strongly advise them not to delete the archived files until they are sure they don't need them. With a one click restore, they can easily recover from mistakes as long as they follow that advice. In a way, strange as it may sound, I think it could be a teaching tool since they will be able to see the potential damage from permanently deleting stuff they don't understand. "explain users what they should delete and what they shouldn't?" Definitely that would be good, maybe with some diagrams showing how the files are linked and some info on how some files are used by many Poser items. "Disabling that feature untill the user considers himself as skilled enough" True. It's not unusual to have an "expert" mode. I don't know, maybe I'd have the delete archive in "normal" mode and actually allow deletion in "expert" mode. No way to control whether they actuallr are expert or not unless you want to make them pass a test before they can get to expert mode :-) I know whatever you come up with will be as great as the rest of P3dO. I'm off to test the latest version. Looking forward to seeing what you create.
