Vista - getting windows live mail to move emails into a folder of your chossing

Hi all, I use windows live mail with googlemail and got it set up in windows
live mail as a pop3 account and that does me great, I have all my i-tunes
receipts going into a I-tunes folder in googlemail at the server end but
when I download the mail into windows live mail it goes into the inbox for
googlemail. how can I get it sort up like it does for my windows hotmail
account so all my filters at the server end work like hotmail's filter's do?
do I change the protocol from pop3 to imap for it to do what I want it to do
or do I have to add a filter in windows live mail? thx
