I hate sync and have managed to get duplicate copies of books on my reader because one is on reader and one on SD card. I have a new computer and I want to get rid of sync function. I have loaded Library 3.1 on new computer but done nothing else. On my old computer I have divided my books into those I want on reader and those on sd card with no duplicates. I plan to reformat my reader with the sd card removed to get a clean slate but I assume I first need to get books from either old computer or reader to new computer. How can I go that without getting duplicates again and being sure that sync will be off on new computer?
