You may have some music on Windows Media Player, and you want to add them into iTunes library for your new iPod or iPhone. Or you may want to move your iTunes bought music to Windows Media Player for portable devices such as Zen, Zune, Phone, Sansa, Archos, MP3/MP4 Player, etc. It’s easy to do that. And this guide will show the steps to do the job.

Part1. Transfer Windows Media Player music to iTunes

Step1. Open iTunes and select the File -- Add Folder to Library menu.

Step2. Browse to your Windows Media Player music folder. iTunes will ask you where your songs are located, which by default will be in your My Music folder on Windows XP, or in your Music folder on Vista.

Step3. Convert Windows Media Player songs to AAC format (.m4a). If you have files in WMA format, you will be prompted to convert those WMA files to AAC. This is a necessary step if you want those tracks available to play on your iPod or iPhone. If you have a large music library in WMA format, converting WMA to AAC may take a long time. Plan to do this at a time when you can leave your computer on and walk away to do something else for awhile. You can also import your WMA files as MP3 instead, which also allows them to work with your iPod, but makes them more portable if you buy something else in the future.

iTunes doesn't modify your original music files from Windows Media Player. It leaves those songs in their original location and makes copies in your iTunes music folder.
