Ok I think that I have missed something. I seem to use huge amounts of disk space on my laptop storing all the tracks. And so in nice easy steps.... I have Itunes and an Ipod mini. Standard configuration on iTunes. I copy the (required/favoured) tracks from cd's into Itunes. I update the mini. Things work fine. The problem is that I have a work laptop with only a 9gig HD. The HD is now filling with music tracks and will soon run out of space (only 1.5 gig used for itunes so far but only 0.5gig left on HD) Is it possible to remove the tracks from the Computer without removing them from the mini, the next time i update it.?
