    Databases in Exchange Server 2007 are still based on a more or less unchanged Extensible Storage Engine (ESE). As most of you are aware, ESE relied on two databases files, an .EDB and a .STM file.

    The purpose of the streaming file (.STM) was to house raw Internet content message streams as defined in Request for Comments (RFC 822). Since the .EDB file isn’t very suitable for storing raw Internet content message streams, the idea of introducing the .STM file was understandable, but with Exchange Server 2007 the .STM file has been removed together with the Exchange Installable File System (ExIFS). The reason behind this decision was in order to reduce the overall I/O footprint for Exchange Server 2007.
