I bought a iPad for school for the sole purpose of reading my textbooks while commuting. This is my first iPad and all my other devices are Android-based. Surprisingly, unlike any of my Android devices, I cannot simply connect my iPad to my computer and transfer files directly to the iPad. All of my textbooks are either in .pdf or .epub format. I simply want a way to store all of my textbooks on my iPad and view them from either iBook or Adobe Reader. I have well over 100GB of space on my iPad so that is not an issue. I already thought about emailing a version to myself but most of my textbooks are well over the email size limit. I also tried Google Drive (since all of my textbooks are already synced through that) but I get, "Unable to Open File. Try opening this file in another app." If I click on the Open In... button, and then click on the "Open In" option, I get, "The file could not be downloaded." If I click on "Add to Reading List" and then go to iBook, the .pdf does not appear. The issue is definitely not my textbooks since all of them can be opened and downloaded on every computer I have. I just want a way to store my textbooks and view them as I choose. I do not want to use iTunes; however, I would consider jailbreaking the iPad if this would allow me to use it similar to my Android devices.
