[http://wiki.mozilla.org/User:Emre/tb/architecture/diagrams/messagefolder <code>Folder</code>] is the logical entity that contains message contents belong to the same hierarchical level. Message content consists of message headers and message body including attachments. These two entities are stored in different physical stores to improve the system performance.
