  ComObj; 
 
function IsNTFS(AFileName: string): Boolean; 
var 
  fso, drv: OleVariant; 
begin 
  IsNTFS := False; 
  fso := CreateOleObject('Scripting.FileSystemObject'); 
  drv := fso.GetDrive(fso.GetDriveName(AFileName)); 
  IsNTFS := drv.FileSystem = 'NTFS' 
end; 
 
procedure TForm1.Button1Click(Sender: TObject); 
begin 
  if IsNTFS('X:\Temp\File.doc') then
