I installed the Overdrive app so I can download and read library books and set it to download to the Micro SD card instead of the device. However, when I look on the DS card, the book isn't there and I can still read it with the card out of the slot. What happened? I did have Overdrive configured to download to the device, but then changed it to the memory card before getting the book. I see people telling they can read eBooks on Adobe Digital Edition on their PC and that's what I wanted to do as well. Is there a way to move the book from Overdrive to the Micro SD card?
