You can copy licensed files using Portable Device in the same way you copy any other content to your portable device. When you copy a licensed file to your portable device, Microsoft Windows Media Player copies the license too.
When you copy an audio file to a portable device, you can compress the file so that it uses less space on your portable device. By default, Windows Media Player will compress all files to a bandwidth of 128 kilobits per second (Kbps). If your file is smaller than this, it will not be compressed. You cannot use Windows Media Player to resample a file and make it sound better by selecting a larger bandwidth.
Note To transfer a licensed file, your portable device may require a hardware serial number. The person or company that provides a licensed file decides license rights; not all files will work after you copy them to a portable device.
