I have an ipod touch and very limited space on my pcs hard drive so I want to add my itunes films to my ipod touch and then be able to wis them from my pcs hard drive. it keeps syncing and deleting my ipods films though! What can I do?

For the ipod to be able to sync it needs the files to still be on the computer sadly. One option would be never to sync it again, which isn't a practical thing. But if you're running out of space on your pc's hard drive u might want to think about getting an external hard drive. They're going down in price and it would help with the space issues.
