I can also modify a file with a hex editor so it fails to be read with any
code i want it to fail with.
what kind of argument is that supposed to be?
i can create a file that works without your patch and fails with your patch
for example if i wanted
The questions are
1. Do such files exist out there
2. if yes, why does our code fail
once we know why it fails we can think about how to fix that.
