Is there a way to prove that you did?
If yes, your jailers may say "We know you have more self-incriminating
evidence there. Your imprisonment will continue until you prove that
you've given us everything."

Get it?
So in theory you
could hide the nasty stuff behind the second passsword, a ton of innocent
stuff behind the first password and just give them the first password
when asked.
If the encrypted file is large, and disk file fragmentation patterns,
timestamps, etc. suggest it has grown through reallocation, the 4 KB
grocery list you decrypt out of it is not going to convince anyone.
On the other hand, if you produce a sufficient amount of relatively
incompressable image, video, or encrypted data from it, you may be able
to convince them that you've decrypted it all.
