Apple has just added the ability to share files on its MobileMe service. File sharing on MobileMe was initially promised by Apple in July 2008, and has now finally arrived. You simply log into your Me.com account, and then you can easily upload and share any file stored on iDisk. You can also set an expiration date for your files and protect select files with a password. You can check out the Apple video tutorial that shows you how easy it is to share your files via e-mail and so on.
