In actuality, I'm planning to create yet another big project, for which saving every bit of memory is going to be needed. Unnecessary references to links get loaded and oft remain in the device's memory. In a 250kB book this does not make much difference, but in creating a bible with structure, probably could... I'm planning on creating a bible. If you look up my "bible framework" on mobile read, you'll notice it has well over 3.000 links in it. I made a KJV bible a few years ago for the Sony Reader (in LRF format). I made the bible entirely out of a single HTML file. Every book included contains links to chapters, and each chapter contains a link to the toc and previous and next chapter. The bible I created for the sony, would not function properly on the sony (although it would on a computer), probably because of lack of memory, because of too many hyperlinks. For that reason I'm keen on trimming as much as possible. If things go the way I suppose they go, I could choose to get the books defined in toc.ncx, and use in-document hyperlinks. If I would create every chapter link in the toc.ncx file, that file would well exceed 200kB, and I don't know how any reader would handle that... |

So far no problems yet.... I don't know if 7z did any better compression than the original ebook. It may have used the same algorythm as used in the original archive... |

So if you leave it out, you don't have an epub document. It's that simple. |

still, you can include the ncx file, but leave it virtually empty?

The way to get to the ToC in an ePub uses toc.ncx. |

There is a program you can use with Windows to properly compress an ePub. It's called ePubPack. The link below is to the thread that contains the link to download the program.

This is a known problem with some Sonys (and probably other models of reader), which is why the recommended course of action is to split the HTML into separate files, so the reader can load things a chunk at a time, usually based on chapters (and this may have to do with why Calibre often auto-splits stuff as well).

The limitation on Sony is for HTML files only afak. You must make sure that each HTML is not larger than 280 KB uncompressed.

Then they're split into separate "flows (ie files) within the ePub. As has been said, the maximum flow size that the 505 will work with is around about 280kb.
