What was the major different?

The only difference I see is the file size.

Same here. There is no diff at all.

So why is this one considered the parent post if they're no different whatsoever from the child post? What puzzles me even more is the redundancy behind this post.

Does it really matter? They were posted at the same time, so choosing one as the parent is gonna be arbitrary one way or the other. The redundancy isn't a big deal, Albert said that duplicates don't matter.
