Maybe someday we will need look-up indexes by Author/Title/ISBN etc. That’s not our world right now.
The default scheme for download files is to have a single .zip archive file for a book that is named for the author, the book subject, and a release number. The release number is increased if changes are made to the contained files. Look for Readme files and similar guidance as separate files that are contained within the .zip archive file.
