Microsoft is making available 5GB of free online file storage via their Windows Live SkyDrive service. Users can upload files that they want to backup, make available to themselves online, share with a few select people or make available to the world.
Windows Live SkyDrive works on Windows or Macintosh computers with Firefox 1.5 or higher, or Internet Explorer 6 or higher. A Windows Live ID is required to use this service, so if you use any of the other Windows Live features (such as Hotmail, Spaces, etc.) you will already have an account.
