So if that epub is one 900+ KB xhtml file, then yes, older ereaders will not be able to open it.


IMHO, it's much better to break out each chapter as individual files, or, if you have small chapters in larger sections, then make each section an individual file.

I don't know of any negative impact from have lots of small files. I'm sure someone here has different ideas though!

It offends those folks that think every book should just be one huge linear file, with no chapter breaks (ADE based readers start a clean page).
The advantage is, when using the TOC (or link), to change from chapter low to chapter high is just 1 small file load. The other way, the reader has to search the entire file for the anchor point
