Module Name:

  WinNtSimpleFileSystem.h

Abstract:

  Produce Simple File System abstractions for a directory on your PC using Win32 APIs.
  The configuration of what devices to mount or emulate comes from NT 
  environment variables. The variables must be visible to the Microsoft* 
  Developer Studio for them to work.

  * Other names and brands may be claimed as the property of others.
