So I have used the google and searched these forums and I just can't find anything. Presumably it's because I'm dense and the answer is right in front of my face so there's no need for the rest of the world to address it.
To unlink tables, one must simply delete the table. Don't worry, though! You're only deleting the link and not the data, says Access and the Internet.
Cool. I really need that data.
Then I delete a linked table and it disappears.
What the hell am I missing?
