I recently tried
www.mediafire.com
It is a free and safe site for moving big files around. You upload your file to it, and then send a link to your correspondent. They click the link, and down comes the file.
This site was recommended by PC World Magazine, so I think it is quite safe. I've used it a few times to send stuff to my kids, and there has been no sign of ads, spam, or malware as a result.
