Problem compiling "CloudStorageServiceDemoVCL" demo program with delphi 11

Hi Bart, thank you for your very quick reply.
However there is a little problem more ...
When i click on "UP" button the program "reload" the main root ..... even if i'm in a sub, sub, directory.
This because the Currentfolder.ParentFolder is always nil.

To avoid this situation, i made a little change like that; maybe not elegant but do the job. If you think this change can be usefuly to someone, please update the code.

In the demo, under form's private declaration add

LastParentdir : TTMSFNCCloudItem;

in "openfolder button" add this line

LastParentdir:=CurrentFolder;

before
ci := TMSFNCCloudDemoListBox1.Items[TMSFNCCloudDemoListBox1.ItemIndex].DataObject as TTMSFNCCloudItem;

and the upbutton will be

procedure TForm4.btUpClick(Sender: TObject);
  function LastIndexOf(const S: string; const Chr: Char): Integer;
  var
    i: Integer;
  begin
    result := 0;
    for i := length(S) downto 1 do
      if S[i] = Chr then
      begin
        result := i-1;
        break;
      end;
  end;

begin
  if Assigned(CurrentFolder)and Assigned(LastParentdir)  (*Assigned(CurrentFolder.ParentFolder)*) then
  begin
    //CurrentFolder := CurrentFolder.ParentFolder;
    CurrentFolder:=LastParentdir;
    lPath.Caption := Copy(lPath.Caption, 0, LastIndexOf(lPath.Caption, '\'));
    if lPath.Caption = '' then
      lPath.Caption := 'root';
    TMSFNCCloudStorageServices1.GetFolderListHierarchical(CurrentFolder);
    LastParentdir:=CurrentFolder.ParentFolder;
  end
  else
  begin
    CurrentFolder := nil;
    lPath.Caption := 'root';
    TMSFNCCloudStorageServices1.GetFolderList;
  end;
end;

After did the update, when click on "up button" the program will reload the real parentfolder instead read the root.

Thank's for attention

Regards
Daniele
