Some little questions about Data Stacks

Hello! I have to create an application for Mac and Windows, and I have read
that, from Rob Cozens.

I have read all the others mails about the same topic. I think that all is
clear but. Hem. Not all in fact.

So, all my data are in a stack that is not include in the builder. It's
correct? Yes? OK, it works by me... I'm able to open the stack and to save
the modifications, in Windows too.

I have read the Tutorial Independent Study. If I have well understood, the
external stack (with data) must have the".edb" extension?

And please, how to protect the stack with data, in order to prevent any user
to open the stack without to pass by my application. But I want to be able
to open the stack from the app, of course!

Finally, is it possible to open the stack in background to prevent the user
to see it?

Thank you for all your answers.

Friendly

François
