Access 2007 File Type Extension


Access 2007 introduces a few new file extensions

• ACCDB The file extension for the new Office Access 2007 file format. This takes the place of the MDB file extension.

• ACCDE The file extension for Office Access 2007 files that are in "execute only" mode. ACCDE files have all Visual Basic for Applications (VBA) source code hidden. A user of an ACCDE file can only execute VBA code, but not view or modify it. ACCDE takes the place of the MDE file extension.


• ACCDT The file extension for Access Database Templates.

• ACCDR is a new file extension that enables you to open a database in runtime mode. By simply changing a database's file extension from .accdb to .accdr, you can create a "locked-down" version of your Office Access 2007 database. You can change the file extension back to .accdb to restore full functionality.
