Use a free web based email account as ftp storage.
Gmail is pretty large, free, and easy so use , works with POP3 clients like outlook,oe, thunderbird...etc... just send the file to yourself, and set your email client to leave messages on server.
Easy to use, and the price cant be beat. need more space, open more free accounts. All this will cost you is time.
And all you need to access your files from anywhaer globally is the email username,password and a internet connection.
