Here is what I use:
I add a 2nd form to the project and add 2 panels, 2 buttons, 1 Treeview, and 1 ImageList (not shown). To the ImageList, I add an open folder icon and then a folder icon and I point the TreeView ImageList property to the added ImageList.
Here is the code for the folder browser:
public partial class LFFolderBrowser : Form
{

// 1 = Cloud
// 0 = On Prem
switch (iLoginType)
{
case 1:

if (lfbCloud.IsDisposed == false)
{
if (lfbCloud.ShowDialog() == DialogResult.OK)
{
tbLFPath.Text = lfbCloud.Path;
}
if (lfbCloud.IsDisposed == false)
{
lfbCloud.Dispose();
}
}
break;
default:
