I am accustomed to uploading a single html file (zipped with images where necessary) for publishing on Amazon's Kindle platform. When I converted the html to epub (using Sigil, of course!) for Barnes & Noble, I dutifully hacked it into chapters, breaking the file into as many segments as there were chapters, plus the title page etc etc.

Today, as an experiment, I uploaded an epub file for Kindle conversion that was a single block. It converted perfectly. (I can tell no difference between the epub conversion and the html file I uploaded a few hours earlier, when each is viewed on the Kindle Previewer software.)

I understand that there are some e-book readers that choke on large files. What readers are those, and how large a file? This one for example is 137KB. (The html file shows as 415KB.) Surely that's not a problem anywhere?

(It would really save me time and effort only to have the one version of the book!)

Thanks!
