How can I send a large file of 2.1 gigs in an email?

I used to use SendSpace.com and some others I can't recall which would allow a file to be uploaded to their site and then send an email. Likewise a link would be created so it was easy to just share the link.

SendSpace doesn't seem to be active anymore and I can't recall the other sites.

Which FREE sites are popular now? I won't be sharing massive data, just files with friends which would be too big to send via email.

Thanks.
