Convert a Database to the Access 2007 File Format

The user can convert a database that was created by using Microsoft Office Access 2003, Access 2002, Access 2000, or Access 97 to the new Microsoft Office Access 2007 file format. The user should use the new file format whenever possible because it supports new features, such as multivalued fields and attachments. However, a database in the new Access 2007 file format (.accdb) cannot be opened or linked to with earlier versions of Access, and the new format no longer supports replication or user-level security. If the user needs to use the Access 2007 database with earlier versions of Access, or if the user needs to use replication or user-level security, he or she must use a file format from an earlier version.
