You can write it yourself. If the recordset is relatively small, the easiest way is to use a TStringList.

var
  i: Integer;
  s: string;
  SL: TStringList;
begin
  SL := TStringList.Create;
  try
    while not RecSet.Eof do
    begin
      // Clear string for the next row
      s := '';
      // Loop through the fields in this row, creating a comma-separated list
      for i := 0 to RecSet.FieldCount - 1 do
        s := s + RecSet.Fields[i].Value + ',';
      // Remove unnecessary final comma at end
      SetLength(s, Length(s) - 1); 
      // Add to the stringlist
      SL.Add(s);
    end;
    // Save the stringlist content to disk
    SL.SaveToFile('YourFileName.txt');
  finally
    SL.Free;
  end;
end;
