I have installed iFile and iBlueNova for the purpose of sending e-books from my iphone to my new KOBO e-reader using Bluetooth. How do I find the e-book files using iFile? I can find the KOBO app using iFile, but where are the epub files? So far, I just have the trial iFile installed but very happy to buy the app if I can find the e-book files. Many thanks!
