Error: package.opf is over 300KB

Hi All,

For one of the EPUB package I have; EpubPreflight Version 0.1.0 shows an "Error: package.opf is over 300KB".

Whereas EPUB Best Practice 1.0.3 does not say that OPF file should or must be below 300KB uncompressed. The best practice guide only mentions size limitations of XHTML chunks and Image (10MB).

I guess OPF does not directly contribute to open EPUB file on mobile-devices or SonyReader device. OPF is just a packaging file; which has references of all items used in EPUB package. Hence it not should give any problem while reading a EPUB (with OPF>300KB) on SonyReader.

Any comments?

Cheers
Vikas

This is a restriction specific to the very old implementation of the ADE firmware that the Sony 505, 300, and 600 use. Any other reader will be able to read your book just fine.
