+CDFS File System Driver
+=======================
+
+The CD-ROM file system driver (cdfs) sample is a sample file system driver that you can
use to write new file systems.
+
+Cdfs is a read-only file system that addresses various issues such as accessing data on
disk, interacting with the cache manager, and handling various I/O operations such as
opening files, performing reads on a file, retrieving information on a file, and
performing various control operations on the file system. The Cdfs file system is included
with the Microsoft Windows operating system.
+
+## Universal Windows Driver Compliant
+This sample builds a Universal Windows Driver. It uses only APIs and DDIs that are
included in OneCoreUAP.
