Okay...they are not going to be visible any longer because by default Articles hides all its children in the Resource Tree. And since you did not create these resources with Articles, or import them properly into Articles they are not true Articles resources; that's the reason you can't see them even when you open the Articles Container.
If you knew their
id number you could manually edit them, in order to change their parent.
yoursite.com/manager/?a=30&id=378
Or, what I do: install the Addon called
batcher, this would certainly save your life now or someday.
Batch can view all resources no matter where, even if they hide in hell.
Go to the top menu in Manager / Components / Batcher .... look for all the lost / hidden resources; tick them, right-click, change parent.
