duplicate error epub3 but not epub2

kaiaua · 05-20-2020, 05:42 PM

I'm making ebooks from Indesign cc, fairly simple text ebooks with a couple of logo images - 3 pages in book form: a ToC page, a copyright page and the text page. When I export the book to reflowable epub using epub 2.0.1 the finished book validates fine. When I export it to epub 3 it comes up with this error:

ERROR OPF-060 .\Bill Direen\Coma\Final Indesign Files\Coma Final.epub Duplicate entry in the ZIP file: 'OEBPS/toc.xhtml'.

I've run the epub in Calibre and it comes up with the KeyError popup, without being able to fix it, and I'm not sure how to.

I recreated the entire book in Indesign, new book chapters, new ToC and new copyright page, new book file, the same thing happens though - epub 3 throws up the error.

Any ideas?

so out of interest, to answer the problem, for some reason in the epub3 format, indesign is creating two toc.xhtml files, one with capital letters TOC.xhtml, and one with small letters toc.xhtml, in sigil I deleted one of them and saved it and the book validates fine. I don't know what the cause was though.

well, I may as well finish it off. The cause was the Indesign TOC file was named TOC! With a longer name it worked fine.

Strange. Thanks for posting the solution/workaround though.

Too often this happens:
