Sort of, better program, faster with less resource usage.
And I made an error, did a very quick scan of the link.
At first glance I assumed it was another program for file concealment within image data. Of which there are a nmuber.

That's what I get for not taking just a bit more time. Sometimes I don't look closely enough when I'm hurrying.
