Well, no, not really. It's only required that a few bytes at the
beginning of the file are in the right place for "file" to say that it's
a zip file.

file is a useful tool, but it is very frequently wrong

zipinfo and jar similarly will only tell you that the index is in place,
but it says nothing about the integrity of the rest of the file. You
only find that out if you try to unpack it, when zip will say that the
checksum failed
