var
strStream: TStringStream;

strStream := TStringStream.Create('') ;
try
RE.PlainText := False;
RE.Lines.SaveToStream(strStream) ;
Result := strStream.DataString;
finally
strStream.Free
end;
end;

procedure TForm1.Button1Click(Sender: TObject);

RichEdit1.Lines.LoadFromFile('e:\123.rtf');
Memo1.Text := GetRTF(RichEdit1);
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
RichEdit1.Lines.LoadFromFile('e:\123.rtf');
Memo1.Lines.Assign(RichEdit1.Lines);
end;
