Not a byte sequence. It has to be a file, in something that we would recognize as being a filesystem. The bytes have to be the same start to finish each time. The title and metadata don't. We should exclude files of length 0 because those weren't "copied".

I think it's probably either the GPL, or some file which was present in every copy of Windows unchanged since 3.1. Which are there more bit copies of by now, Windows or Android? How many copies of GPL 2.0 are present in an install of Android?
