Troubleshoot an access connection ACCDB unrecognized database format exception

The database suffix name before Access07 is *.mdb and the connection string is written Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\myfolder\*.mdb; Persist Security Info=false;
However, Access07 and ACCESS10 changed the suffix name to *.accdb. The "Unrecognized database format" exception is reported by the above connection.
It is important to note that the MICROSOFT.JET.OLEDB.4.0 OLE DB connection method is the older connection method, and the OLE DB connection mode after 07 will be changed to microsoft.ace.oledb.12.0.
The changed connection became the Provider=microsoft.ace.oledb.12.0;data source=c:\myfolder\*.accdb; Persist Security Info=false;
