System and custom lists and folder trees.
Folder structures are recreated with a self-join of ALL_LISTS parent and ALL_LISTS child where child.AL_FATHER_ID = parent.AL_ITEM_ID. For top level nodes, AL_FATHER_ID = 0.
In addition, each child node inherits the AL_ABSOLUTE_PATH of its parent node and appends three more characters. For example, the children of the node with path AAAAAA have paths AAAAAAA, AAAAAAB, AAAAAAC, and so on.
