Missing Container.xml File Error

[KevinH]

For the record, a valid epub (zip) contains at its root level an uncompressed mimetype file and a META-INF folder that contains a container.xml file. This container.xml file tells you where to find the opf file (in Sigil this is always called the content.opf).

Here is a short example container.xml file:

<?xml version="1.0"?>
<container version="1.0" xmlns="urn:oasis:names:tc:opendocument:xmlns:container">
   <rootfiles>
      <rootfile full-path="OEBPS/content.opf"
      media-type="application/oebps-package+xml"/>
   </rootfiles>
</container>

Thanks. That's a good addition to my notes.

It's really hard learning all these quirks when you're just starting, especially when you're targeting multiple epub formats, ereaders, etc. So I just used my first epub as kind of a guinea pig, learning from my mistakes.

I've found if you make your ePub's as simple as possible it will work in more places than not.
