Bit of a reverse of a common question.
Is it possible to connect a file GDB to MS Access, either to feed data or to use it as an interface?
It seems like Access doesn't recognize file GDBs by itself, but I was thinking maybe using ODBC?

There was also this question, where someone says it'd be possible to make one using the API, but not sure if anyone ever did that FGDB ODBC driver? - Esri Community
