For some of my books I would like to keep some additional files with the books. These files include things like worksheets, files I downloaded from the authors website such as code listings, and my own notes. As calibre only allows one file per format, and renames the file, my solution is to zip up the extra files and add the the zip file as an extra format for the book. This seems to work well. I can open the zip file from calibre and open/add/remove files. My question is - is this safe to do? Does calibre care if I modify the format files in the library (I know I can't rename or move them)? Will calibre avoid modifying or processing these zip files in any way?
