Backing up itunes for a c drive format?

[Northy]

Now then guys, time has come to format this pc and start afresh, I know how to backup/save everything apart from itunes.

How can I save everything so I can put it back the way it is now on the new installation?

Can you have itunes on more than one pc at once? Will it think I'm trying to use two pc's? The Mrs said when she tried it on our other pc it moaned and said you can only connect it to one pc, but I didn't look into it.

So guys, what's your advice?

Cheers,

G
