I was emailing someone today about this question: "How do you know when you have downloaded a complete book?" I heard someone say to check how many items are in the unzipped folder then compare the number of items after the unzipping is done. My example; 105 megabytes, 22 items in the zipped folder and 21 items unzipped So are the items in each folder supposed to be equal or one less? I also have been told that 1 hour listening time equals 11 megabytes. That would give me 105 MB or not quite 10 hours of listening. My V R Stream says the book is 9 hours, 55 minutes and 44 seconds long. Now 10 hours is close enough for me. I didn't want to jump through the book heading by heading. Oh by the way the book has 26 headings. Sometimes the length of the book on the BARD site is not quite accurate.
