I formated my Mac after a few years of work and forgot to do books backup because iPad was lightly used. As a result all my books stuck on the iPad and if I want to add some new from a computer it wants to erase the existing books.
With iFile, I tried to copy books, but there are only folders, not epub files.
So is there any way to get them back or somehow combine with new iTunes library? In general I don't need those books readable on mac, just to restore and the ability to add new ones to the iPad.
