Import media from a computer to iTunes on PC
If you have audio or video files on your computer, you can import them into iTunes so they appear in your iTunes library.
To add media from Audible Manager to your iPod, iPhone, or iPad, you need to first import it into iTunes.
In the iTunes app
on your PC, choose File > Add to Library or Add Folder to Library.Locate a file or folder, then click Open.
If you add a folder, all the files it contains are added to your library.
Tip: You can also drag a file or folder from the desktop to the iTunes window to import it.
By default, adding items to your iTunes library creates a reference to the file’s current location; the original file remains in the current location unless you select “Copy files to the iTunes Media folder when adding to library.” For information about copying files to the iTunes folder instead of creating references to them, see Change where your files are stored. If the file is an unprotected WMA file and you have Windows Media Player Series 9 or later installed, iTunes makes a copy of the file and adds it to your iTunes library. The original WMA file remains unchanged. You can’t add protected WMA files or protected WMV files to iTunes.
