The current trend is to save most of your files in cyberspace rather than in your local computer or USB drives. This gives you unlimited 24/7 but secure access to your files using any computer.
Google docs is 1 way to do it. I am adding it to the other I have been using: googlegroups, class blog, and slideshare. I am trying to totally eliminate sending files as email attachments.
