Hi, I am new so I am sorry if I am posting something that has already been answered by I have searched the forum and could not find my answer. I am an extreme novice to Calibre so just learning all of the technical lingo. I want to merge my friends library with mine. I had read where you need to create a new library so Calibre can "find" it but when I create library it tells me "the folder is not empty please choose an empty folder." I created an empty folder, copied the files to the folder but when I pull it up in Calibre no books appear. Can someone tell me, or show me, the step by step instructions on how to do this. Thank you in advance.
