Nothing happen to see the Memo and also the Label which is quite on progressing hash generated on Delphi FMX. But the result works fine.

Generate with the directory

function GenerateHashMultiCallback(FileName: WideString; FileSize: extended;
  FileProgress, TotalProgress, TotalFiles, FileCounted,
  StatusCode: Integer): Boolean;
begin
  Form5.Label9.Text := Format(XH_FILENAME, [ExtractFileName(FileName)]);
  Form5.Label10.Text := Format(XH_FILEPOSITION, [ByteOrTb((FileSize * FileProgress) / 100), ByteOrTb(FileSize)]);
  Form5.Label11.Text := Format(XH_PERCENTAGE, [FileProgress]);

  Form5.Label12.Text := Format(XH_PERCENTAGE, [TotalProgress]);
  Form5.ProgressBar1.Value := TotalProgress;

  case StatusCode of
    H_FILE_HASHING_DONE:
      Form5.Memo1.Lines.Add(FileName + '  ... Done!');

    -1,-4,-5,-6,-7,-8,-9,-10,-12,-13:
      Form5.Memo1.Lines.Add('>>> Error code:  ' + IntToStr(StatusCode));
  end;

  Form5.Label14.Text := Format(XH_GENERATESTATUS, [FileCounted, TotalFiles]);

  ProcessMessages;
  Result := CancelAll;
end;
