Connect your iOS device to your computer with a USB cable to sync music, movies, TV shows, and audiobooks using iTunes. You can also back up your device using iTunes.

If you want to copy files between your computer and apps on your iOS device, use File Sharing.

You can find iOS apps, ringtones, and books (PC only) that you've already downloaded in your iTunes Media folder.

If you have an iOS app, ringtone, or book that's no longer available for redownload, you can move that content to your iOS device while plugged in to a computer with a USB cable.
