how to open epub files on my ipad?

Open your ePub files on the computer. Use the application like a adobe's Digital Editions software, Calibre or the Barnes and Noble's eReader to just open the ePub eBook on the computer. While reading the whole eBook file on the computer may not be the most optimal way to just read a book, it allows a very quick and very easy access to the ePub file. Open the ePub file on the iOS device. Apple's iBooks eReading application always supports whole ePub format, allowing you to just read the eBook on the iPod Touch, iPhone or the iPad. You can even easily sync the ePub file to the iOS device using the iTunes whole media management application.
