[@Always] Or for the ones who already found their files: It might be easy to find them, but it could be like they are in a box or locked up with something nobody can open on their own, so everybody needs to find someone who can open his files for him. A temperature lock, a code hidden in somebodys memories or a riddle, that only one person but not the owner of the files can solve, or a key, that somebody else found under his personal things. So the task would not just be to corporate in a group but also for getting to know eachother better.

They wouldn't know the file was inside, unless it is a clear case. And any clear case on top of being obvious would be breakable if you're smart. These are criminals, they will resort to conflict and pushing apart
