I have just purchased a kindle book from Amazon and told it to download it to my PC. I can open it and read it off line so it must have it stored somewhere but I can't find it.I'm using win 7 and looked in C:\Users\Bill\AppData\Local\Amazon\Kindle and according to what I read there should be a folder content under the Kindel folder. But there is not one. I opened Kindel for PC and can read the book OK even with the internet connection turned off. All my books are epubs but I could not find this one as an epub or else that is what I would have done. This appears to be very cumbersome.
