Start with a TreeView[^] and an ImageList[^]. The Imagelist contains the icons for the "open" and "closed" folders and you assign the value to the node as it's branch opens and closes using the TreeView.BeforeExpand Event (System.Windows.Forms) | Microsoft Docs[^] and TreeView.BeforeCollapse Event (System.Windows.Forms) | Microsoft Docs[^]
Give it a try, it sounds more complicated that it actually is!
