Filter Manager

The Filter Manager component provides the infrastructure for a new, simpler way to integrate file system filters into your system. These new filters are known as mini-filters. File system filters are used by antivirus and other applications.

Filter Manager is compatible with legacy file system filters.

This component includes the following files:

  • Fltmgr.sys is the Filter Manager driver. It is a kernel-mode file system filter that you implement by using the legacy file system filter architecture.
  • Fltmc.exe is a command-line tool for loading, unloading, and displaying mini-filters.
  • Fltlib.dll is a library of Filter Manager functions that user-level applications can use to communicate with the Filter Manager, as well as with their mini-filters.
