Thanks,
At least the book file will be named the same and the body of the book will be unchanged (only the comments) so maybe? I'll have to look into what "free format book description" is and where it's located (couldn't find anything with a quick search). I'm going to use Bookari (with epub) as it seems for me to be the best option with all it's features. I'm going to look into some of your suggestions as well. All i really want is for one or two lines of text to be inserted into the epub file (comments), that's all....so they will be part of the epub file and travel with the book (to make it easy when i have to move to a new device, and also automatically readable in both Calibre and Bookari). Thanks again for your time with this, i'll do some more research and post back should i find a solution...or have more questions!
