We all hit the universal email to send files across the Internet.But it is not possible to send large files.
WeTransfer (beta) is a simple and free file transfer service that lets you send you files upto 2GB in size.it is absolutely free service.No need to register a Account. Just like your e-mail attachment.Pick the file you want to send. Enter your email and that of the recipients. Type a message and hit transfer.
WeTransfer will hold the file for 2 weeks and sends an email to your recipient with a link to download.
There are plenty of sites to send large files across but WeTransfer.com is a cool and easy name to remember.
