Most email providers have a limit on the attachment size (like 10 megs). Since ur file is 700megs its not gunna fit in one email. You can rar up the file and split into multiple files (say 10megs in size) and email them (its gunna be like 50 emails) and have the person extract the file from the rar archive.
You can also upload it to a server such as rapidshare or something and just email the link.
Other options include using a P2P program (like bit torrent) or an IM client (like skype or AIM) to distribute the file.
