Well, THAT was fun.
I found one of my problem books, and selected Tweak ebook. When I clicked Explode, I got the message, "This MOBI file contains both KF8 and older Mobi6 data. Tweaking it will remove the Mobi6 data, which means the file will not be usable on older Kindles. Are you sure?"
(shrugs) Sure, what the hell. I don't really READ on them that much, they're just around to see the history of the Kindle, how we got to where we were and how it all started... Plus, how old IS older, anyway? So I went in and edited the 20 HTML files that had the random line breaks and Rebuilt the book. It looked pretty good in the E-book Viewer, but it does seem to have picked up some blank pages at some chapter breaks. In the title bar, the original shows up as [KF8:joint] and the edited book is [KF8].
The problem comes when I try to open the book on either my Touch or my Paperwhite. I get a message that "The selected item could not be opened. If you purchased this item from Amazon... etc." However, it DOES open correctly on my 1st gen Fire, and the blank pages aren't there, either. So the question arises... How old IS older? The Fire came out before the Paperwhite, didn't it? I was thinking maybe K2, K3...
Should I try exploding the book AFTER converting to AZW3? I'm guessing that anything to do with the existing, rebuilt book should not be trusted. Does anybody have a link to some guidelines as to the requirements and process of tweaking a book? I tried searching in my 2011 copy of the manual, the current online manual and searching the calibre forum but found nothing in the manuals, and lots and lots of hits on tweaks and ebooks, but nothing appropriate.
As always, thanks for any and all help. I'm done for the day, but I'll be experimenting again on the morrow.
