How to create an OCF file

Hi,

Noob question on exporting EPUB ebooks in Calibre. I created an EPUB ebook in Calibre (by converting a Word doc and fuzting with the output of the conversion tool). Calibre stores the ebook in a file folder (Windows), but I want to be able to distribute it myself. It seems to me that there should be a simple way to export it as an OCF file, so that it can be sent around (e.g. by email) and opened in whatever reader someone else uses. But I can't find how to do this, except maybe to create a ZIP archive and just rename the filename extension.

How do you do this?

Thanks for any help!
