I was needing a way to share a few large files with some different individuals and decided to search for free and easy to use online file sharing.
Microsoft has Windows Live Sky Drive. http://skydrive.live.com/
MediaFire “File Hosting Made Simple”. http://www.mediafire.com/
Currently I think Sky Drive requires all parties to have a Windows Live ID, but MediaFire does not. I was able to create the account and share the folder with multiple people using a customized URL. They were not required to create a MediaFire account just to access the files I had made available.
