So a friend's PC has a virus that we can't get rid of, so I'm planning to re-format the hard drive and re-build it from scratch.
Its running Windows XP SP3, and they have iTunes with a whole load of music that they bought from the iTunes store. Some of it, I think, was bought in the days when iTunes still applied DRM to the music files.
Once I have re-built the PC and copied the music back on, I want to make sure the music still plays.
Presumably just copying the iTunes library to an external drive is not enough
What do I have to do to make sure DRM music will still play after re-building the machine? Is there some sort of official iTunes backup method to handle this?
edit: Also, how can I tell whether music in the iTunes library is DRM'd or not?
1DRM'd iTunes songs have the file extension .m4p which is an abbreviation for MPEG 4 AAC audio Protected (DRM). Non-DRM'd iTunes music and music from elsewhere in the MPEG 4 AAC format uses the extension .m4a or .mp4 or .aac – therobyouknow – 2009-12-20T17:13:39.960
