Have you run into a problem sharing large files with others? I hate to print extra handouts and waste paper, but some files are too big to email. If you've had this problem, you should try a filesharing site. Some are free with limitations, some are a pay service. But is you're looking for a place to share a large file with others, start with the ones here: http://delicious.com/astdlincoln/filesharing.
Personally, I've used DocStoc and Wikisend. I'm a huge fan of Dropbox because of it's options. If you have used a filesharing site and would like to share it with others, let me know and I'll add it to the list of resources.
