What is an EDB file?
An EDB file is a database created by Microsoft Exchange Server. It serves as the main repository for the mailbox data saved by Exchange. EDB files store both in-process and stored non-SMTP messages, formatted using a b-tree structure that includes a top-level node and many child nodes.
Priv1.edb and Pub1.edb are the main EDB files used for the Exchange information store. They each have a corresponding .STM file that contains SMTP messages.
