Filter Manager and Minifilter Driver Architecture

The filter manager is a kernel-mode driver that conforms to the legacy file system filter model and exposes functionality commonly required in file system filter drivers. By taking advantage of this functionality, third-party developers can write minifilter drivers, which are simpler to develop than legacy file system filter drivers, thus shortening the development process while producing higher-quality, more robust drivers.
