By taking advantage of this functionality, third-party developers can write "minifilter" filter drivers, which are simpler to develop than legacy file system filter drivers, thus shortening the development process while producing higher-quality, more robust drivers. A simple Windows file system filter driver solution, created mainly for the demonstration and further customization purposes. The main purpose when you develop a file system filter driver is to change file system behavior. It is called at each I/O operation and provides possibility to additionally process its parameters and change its results (“filter” this request). In Windows, there are two types of filter drivers: legacy file system filter drivers and minifilter drivers.
