public class Directory
extends SharedItem
implements Nameable, Removable, SystemItem
This is used to represent directory items. Directories can be used to group File:s into more manageable compartments. Directories can be organised into an arbitrarily deep tree-like structure. For each directory no two sub-directories may have the same name, and no two files may have the same name. However, it is legal for a file to have the same name as a directory.
