Thanks for trying to help me, guys. It's just that I am totally new to this and somewhat confused.

In order to eliminate the ZIP issue, I unpacked the whole structure in a folder. When I add now the index.htm file to calibre (is this meant by "dragging"?), the book has no metadata (filename?) a size of zero MB and it is not really there (can't be viewed, again, upon clicking "view", the folder listing pops up).

Under "settings/behavior" I activated the internal viewer for ZIP files now.

If I add the ZIP file to calibre, all is well as far as the database is concerned, but I can not view the book I can see the landing page only, without the embedded image files and the links for navigation are not active.

A conversion to MOBI produces an empty book, except for the cover image.

Can you please advise what I am doing wrong?

Thank you, Mixx
