It contains: • Images folder - images go here • ISBN number.opf - XML file that lists what's in the container • toc.ncx - This is the table of Contents • xhtml files - The book's contents are in these
- 23. Makingthe Container • Now we make the .epub container that all these files go in. • Create an empty .zip file with whatever name you like • Copy the mimetype file into the zip file (don't use compression on this file) • Copy the rest of the files and folders mentioned above into the zip file * • Re-name the .zip extension to .epub • Then do online validation of .epub file
