No changes were made to the .mdw file format for Office Access 2007. The Office Access 2007 Workgroup Manager creates .mdw files that are identical to those that are created in Access 2000 through Access 2003. The .mdw files that are created in those earlier versions can be used by databases in Office Access 2007.
