Compare Access file security - MDB/MDE vs ACCDB/ACCDE      

System tables are used by Access to make databases function correctly. With a few exceptions, there is very little information available online about most of the system tables.


The purpose of this article is to summarise known information about Access system tables.

It is also an invitation to other developers to add to this pool of knowledge


Some system tables can be viewed & a few can be edited

However you should only do so ....IF YOU ARE ABSOLUTELY SURE WHAT YOU ARE DOING

Incorrectly editing system tables may corrupt your database or prevent you opening it
