I have got them on an micro sd card as well - but can't get them onto pc
and also on an external hdd.
but haven't managed to transfer from either
My old PC is dead & can't do nothing with it.
Are they your CD's loaded onto a computer or did you buy them on itunes. If you bought then on itunes then open itunes and authorise the computer and your purchases should download automatically.
