Professional Database Development Part IV
You can open and even run Access 97 database files, but you can??™t make any design changes. You
can open Access 2002-2003 and Access 2000 database files and make any desired changes to
them. However, you??™ll only be able to use features specific to those versions. Some of the new features
in Access 2007 won??™t be available.
The default database file format in Access 2007 is .accdb. You can convert database saved in a
previous format by opening the database in Access 2007, clicking the Microsoft Office button in
the upper-left corner of the main Access screen, and selecting Convert. From the Convert Database
Into dialog box, give the file a new name with the .accdb extension and click Save.
Change the default file format for new files by clicking the Microsoft Office button,
selecting Access Options, and clicking the Personalize tab.
