Mmmm, midnight fuel. Thanks for the link. I did know that some files and the META-INF folder are at the root.

My comment was based on a simple Google search, in which every answer appeared to confirm the fact that other content related files and folders are stored under /OEBPS. Even the Wiki page on EPUB states:

Apart from mimetype and META-INF/container.xml, the other files (OPF, NCX, XHTML, CSS and images files) are traditionally put in a directory named OEBPS.

So I interpreted that as a requirement, but it appears it's just strongly suggested. Do you concur?

Thanks again,
Tim
