{ 
  Treeview1.SaveToFile('...') doesn't store images. 
  Instead, use the code below. 
}

 { 
 Treeview1.SaveToFile('...') speichert Bitmaps im Treeview nicht. 

 Um auch die Bitmaps eines Treeviews zu speichern, 
 benutze untenstehenden Code. 
}

 // Save 

procedure TForm1.Button1Click(Sender: TObject);
 var
   F: TFileStream;
 begin
   F := TFileStream.Create('c:\TreeView.txt', fmCreate or fmShareCompat);
   try
     F.WriteComponent(TreeView1);
   finally
     F.Free;
   end;
 end;


 // Load 

procedure TForm1.Button2Click(Sender: TObject);
 var
   F: TFileStream;
 begin
   F := TFileStream.Create('c:\TreeView.txt', fmOpenRead or fmShareDenyWrite);
   try
     F.ReadComponent(TreeView1);
   finally
     F.Free;
   end;
 end;
