Anything you want. You can store Office documents, like from Word, Excel, PowerPoint, or Adobe PDF files. You can store movies (though we wouldn't recommend it), pictures, program files, or any other type of file you can think of.
Not by default. When you save a file to your SkyDrive, it is only accessible to you. You can change the settings on folders to be sharable to a certain contact/email address you specify, to a group of people, to your friends, or to everyone.
Consider this example: You would like to share a Word document with a classmate who is in your group.

Send a Link - Send a link to this folder to any email address you specify. For added security, you can require people you send a link to to log in with their Windows Live ID/Live@RIC ID.
Get a link - Receive an actual web address for this folder, so that if you copy it and paste it anywhere, someone can click the link and access the file.
