No sensable suggestion is
useless, if you don't need it right now, it might come in handy later.
I forced one file to open in Wordpad, I got all the markup code with it, but it's all there. I'll spend quite a bit of time picking through the doc to delete it. And feel it's worth every second.
The second one opened the same way, but from about P 10 it's so garbled I doubt anyone could make sense out of it. That one was also somewhere else (a friend who is an Editor). An earlier version, but that may be a good thing. I was close to doing a total rewrite anyway. It kinda got losted about Chap 10 or so.
