A major new capability in SharePoint 2010 is the ability to create Document Sets. A document set is just what it sounds like – a set or package of documents defined as one entity. For example, a loan mortgage application packet could be considered a document set within which you would have individual documents such as personal information, existing properties you own, loan rate declaration etc. Each of these documents could be of any type, but together they make up the document set. This video shows the process of creating a new document set from scratch.
Watch the video on Creating Document Sets that explains this functionality.
