How can I find out the file system being used in Windows Preferably in code

function string get_FileSystem( strPath )
  object objFSO, objDrive;
begin
  set objFSO = CreateObject ( "Scripting.FileSystemObject" );
  if ( IsObject (objFSO) ) then
    try
      set objDrive = objFSO.GetDrive( objFSO.GetDriveName( strPath ) );
      if ( IsObject( objDrive ) ) then
        //Available return types include FAT, NTFS, FAT, FAT32, and CDFS
        return objDrive.FileSystem;
      endif;
    catch
      MessageBox( "Unable to determine File System.", INFORMATION );
    endcatch;
  endif;
end;

Console.WriteLine(new DriveInfo(Environment.SystemDirectory).DriveFormat);
