Folders can contain Message objects, other Folder objects or
both. This nesting capability enables a folder hierarchy for stored
messages. The different levels of hierarchy in a folder's full name are
separated by the hierarchy separator character, which you can retrieve using
getSeparator().
You can retrieve a contained folder by name using
getFolder, or a list of contained folders by
using list(). Both these methods return folders not cached by the
Store owning this folder, so invoking either method multiple times
on the folder returns distinct Folder objects.
Note: Multiple Folder objects can refer to the same physical
folder on device. As a result, you should invoke
addFolderListener to register a
FolderListener to listen for any FolderEvent affecting a
folder. When finished, you can remove the listener with
removeFolderListener.
