There are some big updates that have come to SkyDrive. The updates make it easier to see and manage all of your documents.
The first difference I noticed is that with each file in your SkyDrive there is a small "i" icon to the right, that when clicked, displays a selection pane for the selected file. The next difference I observed was the massive improvement is speed of browsing through your files.
Take a look at the post below for more info.
