Message storage structure

The messaging framework manages message-related data through a collection of entries, which are organized into a tree structure. In addition to the root entry, there are four types of entries:

• Folder

• Message

• Attachment

• Service

The entries are only handles to folders, messages and attachments and messaging service settings. The messaging framework stores the actual message data, including attachments, in the Private folder on the Message Server. To access the stored message attachments, use the file handles provided by the MMsvAttachmentManager class. Do not use directory paths.
