ITunes is required when setting up an iPod or iPad.

When you install Apple's iTunes software on your computer, it creates a folder called Installer Cache for troubleshooting purposes. If you experience a problem with iTunes, you can repair it using the original installation data stored in the cache. However, the Installer Cache folder may also store the installation data for previous versions of iTunes that you no longer use. You can safely delete these older versions to reclaim hard drive space.
