I’m running out of room on my laptop. I only have 204.7 MB of songs on iTunes which I’m desperate to keep. But my laptop needs wiping.

And how do I wipe it. Is there a button or something?

Answer:
burn your itunes on to a cd
Answer:
either backup your songs using itunes or by replicating directly on a pen drive or burning to a CD. to wipe your machine basically means rebuilding it, did it come with a recovery disk? does it have a recovery partition? if not then you will need to install absolutely from scratch using a windows xp or vista installation disk
Answer:
Purchase an external hard drive, put all your songs on there, that will free up space on laptop hard drive for other stuff.
