edb structure
Hi, I am trying to understand the structure of an edb file for exchange server 2003. So, far in my research i have understood that an edb file is logically divided into pages. The first two pages are file header. What i have failed to understand is the structure of a page. Can any body help me in this direction. Thanks, Jude

Does it mean the list of pages page 4 is pointing to in the b+ tree ? Thanks, Jude
