So many files?
I just wondered why the book creation wizard (paperbacks) creates so many files. I upload a single text file in PDF and yet I end up with three files in my list. I upload a cover file in JPEG and I get three or four files in my list. In all cases the files are, to all intents and purposes, identical. I often worry that the printer will use a previous file after I edit a book, because there are so many to choose from in my list. Any reason for so many copies of seemingly the same file?
