Interesting. The reason the author, title, etc. is in the mdp file is to avoid having to open the main file to display this information on the library screen. I can't believe that they open all the files every time they are on the library screen so perhaps they have a second place to store this data. Perhaps there is a cache on the machine somewhere with this data in it. The cache would also have to timestamp every entry to insure it could be updated if you upgrade the eBook itself.
Thanks for the information.
