Hi everyone, I did my researcher and tinkered with it, but I can't find out how to fix this. I guess now PDFs sync through iTunes from iBooks to iOS devices. Well, I had several PDFs from the pre-Mavericks era in iTunes ("iTunes Media" >"Books" folder). Well I imported my PDFs into iBooks so that I could start adding new and managing them, but now all my devices have duplicates showing in iTunes (in the books tab when I select a device) and it tries to sync the old and new. I deleted the Books folder from iTunes Media, but it still attempts to sync those books and I get an error "can find file" when I sync, but most annoying of all is that on the books tab there is duplicates of all the PDFs that were in the old "books" folder and now in iBooks. How can I get iTunes to delete and "forget" the old PDFs without restoring my device?
