A file system filter driver intercepts requests targeted at a file system or another file system filter driver. By intercepting the request before it reaches its intended target, the filter driver can extend or replace functionality provided by the original target of the request. Examples of file system filter drivers include anti-virus filters, backup agents, and encryption products. To develop file systems and file system filter drivers, use the IFS (Installable File System) Kit, which is provided with the Windows Driver Kit (WDK).Fltmgr.sys is the Filter Manager driver.
