It's a complex operation to transfer files between iPhone 5 and computer/Mac with iTunes. Also iTunes has some functional limitations. For example, users can only sync local files to iPhone, but cannot add some specific files without synchronizing the whole library.
To help users conveniently transfer files between iPhone 5 and computer, I highly recommend to all iPhone 5 users the amazing iPhone 5 Transfer. It is a powerful yet easy-to-use iPhone 5 transferring application. With it, users could easily import local music, video, ePub, PDF, image files to iPhone 5, and export iPhone 5 files (music, movie, pictures, TV shows, Podcast, iTunes U, eBooks, Camera Roll, ringtone, SMS, Contacts, voice memos, camera shot) to computer. Also this software enables users to backup iPhone Contacts and SMS on computer.
Besides of transferring files, this iPhone 5 Transfer also allows users to convert DVD and video files to iPhone 5 compatible video and audio formats. Also it can customize output iPhone 5 video effect with powerful video editing features. It can trim video length, crop video frame, watermark video, adjust video effect, and so on.
Moreover, this software can even help users create the unique iPhone 5 M4R ringtones with source DVD, video and audio files. After the ringtone creating operation, this software can directly transfer the created M4R ringtones to iPhone 5.
