What is an accde file and how do I open an accde file?

A Microsoft Access 2007 read-only database file is integrated with database encoding specifications used by the Microsoft Access 2007 software to store ACCDB files in the ACCDE file format. These ACCDB files are Microsoft Access 2007 database files that replaced the older MDB file format. This new file format used for a Microsoft Access 2007 read-only database file has in turn replaced the older MDE file format. The content of a Microsoft Access 2007 read-only database file is implemented with VBA locking functionalities to prevent other users from accessing the VBA code implemented into the database file. These Microsoft Access 2007 read-only database files are affixed with the .accde extension, and the Microsoft Access 2007 is a database management application that can be installed in computers running on Microsoft Windows-based systems.
