300k preflight file error
I'm producing a book with notes throughout and thought life would be easier to have the whole book in one file and the notes in another. For the chapters used "H" headings (for the TOC) with page break before.
The book passed both Sigil and ePubChecker validation, but when it came to PreFlight I get:
ERROR: C:\EBOOK TESTS\Walking to America.epub/OEBPS/Text/maintext.xhtml: file is over 300k in size.
I checked online and best practices "suggest" keeping the file size limit below 300k.
Does anyone have any views on this or should I just ignore this PreFlight "error".
Thanks in advance,
