Re: Transfer audio files from phone to computer
Same way you'd transfer them from drive C to drive D - drag and drop.
Plug the phone into the computer and it should (after a minute or so) show up as a new drive. Open it and you'll see 2 folders - Phone and Card (if you have an SD card plugged in, otherwise the Card folder won't be there). Find the song files or, if you want to maintain the Artist->Album->Song structure, the top folder, and drag it to the computer.
(Purchased songs that are copy protected won't copy or, if they copy they won't play.)
