There are many ways - eg an external Hard drive.
If your friend has a DVD burner, or can borrow an external one, I would burn Photos onto one or more DVD's (4.5 Gig per DVD) and Music on others and Word or spreadsheets on another. I find it easier to keep different applications on seperate DVD's to syop confusing auto run programmes. eMail has an option to export adress book etc - floppy discs probably enough for that. Another way is to link the computers via a wired network - if the old one hasn't a card they are about £10.
