DFS is a feature in Windows Server 2008 that permits an administrator to create one logical filesystem layout despite the fact that shares can be scattered across the network on different servers. This makes it easier for clients to find and store files consistently, and it allows for better equipment utilization. One server can host multiple DFS roots, which are "starting" points for a hierarchy of shared folders. In addition, a Windows Server 2008 server can use Active Directory site topology to route DFS requests from clients to the closest available server, increasing response time.

Native encryption abilities are built into the NTFS filesystem used in Windows Server 2008. By simply checking a checkbox in the Properties sheet for a file, you can easily encrypt and decrypt files and folders to protect their integrity. This feature is particularly useful for mobile computers, which have a greater risk of data loss and capture than traditional corporate desktop machines.

The volume shadow copy feature is perhaps one of the most useful features of Windows Server 2008. The server will take snapshots of files at specific periods during the day, thereby making available a library of previous versions of a file. If a user accidentally overwrites a file, saves an incorrect version, or somehow destroys the primary copy, he can simply click Previous Versions in the Explorer view of the folder and access a shadow copy version.

The Windows Search Service, new to Windows Server 2008, catalogs and indexes the contents of server hard disks, enabling users to search in files in different formats and languages for the data they need. The engine has been enhanced over several revisions of the product to accelerate the search process and to use less processor time when cataloging and indexing files.
