Explanation:
What is the File Classification Infrastructure?
The Windows Server 2008 R2 File Classification Infrastructure (FCI) automates classification
processes so that you can manage your data more effectively. You can save money and
reduce risk by storing and retaining files based on their business value or impact. The built-in
solution for file classification provides expiration, custom tasks, and reporting. The extensible
infrastructure enables you to meet additional customer classification needs by building rich
end-to-end classification solutions that are built on the classification foundation of Windows
Server in a consistent and supported way and within the existing Windows file serving
platforms.
