Title: High performance message store

Abstract: A product and method are disclosed for creating an efficient message store and delivery system is provided. A message store having an index directory, index file, and data bucket area, all of which are page based, is described. Each page corresponds to a period of time, such as a day. Each data bucket contains message data and the actual content of the message. The index file contains index file cells which store index information characterizing an associated message. The index directory contains index directory cells which store information on the location of an associated index file cell, and is thereby associated with a message. It also includes page based user folders each having user cells which reference a message, associated with a user, in the user store. A message includes a reference pointer to an associated index file cell and a reference pointer to an associated index directory cell. An index directory pointer in the user cell, an index file pointer in the index directory cell, a message pointer in the index file cell, and two pointers in the message allow the message store to reconstruct itself if necessary.
