SkyDrive Adds Recycle Bin and Excel Surveys
From there you can browse your recycle bin in thumbnail or details view.
It’s easy to select items to restore back to their original location, as well as see when the item was deleted. And file and folder selection works just like it does in the rest of SkyDrive.
Items in the recycle bin do not count against your SkyDrive storage limit. We save all items you delete in the recycle bin for at least 3 days. If the content in your recycle bin gets large enough to exceed 10% of your storage limit (which will be pretty rare), we’ll start to delete the oldest content (after it’s been there 3 days), and will permanently remove items from the recycle bin after they have been there for 30 days (and not restored).
Right now, the recycle bin feature is available from SkyDrive.com, and over time we expect the recycle bin experience to make its way to other SkyDrive experiences too.
