        private void Form1_Load(object sender, EventArgs e)
        {
            treeView1.Nodes.Add("D:\\");
            treeView1.Nodes[0].Tag = "D:\\";
            DirectoryInfo di = new DirectoryInfo("D:\\");
            DirectoryInfo[] dirs = di.GetDirectories();
            foreach (DirectoryInfo dir in dirs)
            {
                TreeNode tn = new TreeNode(dir.Name);
                tn.Tag = dir.FullName;
                treeView1.Nodes[0].Nodes.Add(tn);
                AddChildNodes(tn);
            }
        }        private void AddChildNodes(TreeNode parent)
        {
            DirectoryInfo di = new DirectoryInfo(parent.Tag.ToString());
            if (di.GetDirectories().Length > 0)
            {
                DirectoryInfo[] dirs = di.GetDirectories();
                foreach (DirectoryInfo dir in dirs)
                {

                    AddChildNodes(tn);
                }
            }
        }
        private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {
            listView1.Items.Clear();
            DirectoryInfo di = new DirectoryInfo(e.Node.Tag.ToString());
            if (di.GetFiles().Length > 0)
