Free! - Box.net Online File Hosting.
Personal file-sharing sites like megaupload and yousendit are still heavily used these days, but I am always keeping an ear to the ground for anything that breaks the mold and offers something new. Box.net has been around for quite some time, but they have completely re-modeled in the last six months and added many great new features.
A free account gives you 1GB of permanent storage and individual file sizes up to 25 MB. Create folders and upload files as usual and send out links to files and folders to anyone you wish. What makes Box.net exciting is the ability to invite "collaborators" by email to upload their related files to your folder as well. With the ability to create web-based documents inside their interface and share everything out as needed to both individuals and groups, personal and business users alike will find plenty of utility in Box.net. If you find that 1GB isn't enough to backup your important files, we actually host our own service for off site backups in Los Angeles that secures entire servers of data.
