Folks, I am trying to add ebooks/PDFs (I already have 2 readers called IBooks and PDF Reader Lite) in my IPAD 4 but it seems I really don't know how to do this properly. * First, what I was going to ask is this: is there a way to access the folders from this IPAD using Windows Explorer and not ITunes? If that were possible, I could see what's inside and add manually to that folder. What I did was this: I opened ITunes, then I selected the "Add files to the library" option. Then I synced my IPAD. Later I noticed some books are not available, I can't find them. And after that, I moved the folder to another location and/or deleted the files from my C:\ Hard Drive. Will that make any difference or the files were already copied to IPAD anyway? There's also an option called "Books - Audiobooks / Books / PDFs / Authors / List", and as you can see here: It looks like some books are duplicated. BTW, this one, "School of Darkness" can't be found in this IPAD. I tried adding again, but it's not there. IBooks can't find it by doing a search for file keywords. What I want is simple: to add files manually and see if there are duplicates, and delete them. And to be sure if all ebooks are there. Because I need to delete those files from C:\My HardDrive, once they are stored in IPAD. The strange thing is the first time I used this IPAD in C:\My HardDrive it was possible to access by Windows Explorer.
