At TechEd 2009, Microsoft introduces the “Windows Server 2008 R2 File Classification Infrastructure (FCI),” this new features allows you to define classification properties, automatically classify files, automate file management tasks (like file expiration) and generate reports that show the distribution of these properties on the file server. The File Classification Infrastructure also provides a great opportunity for partners to extend these out-of-the-box abilities, including the possibility of seamless integration of multiple partner solutions.
