List specific directories in a listview

That is what I am using right now.  Here is what I have up to this point to enter it manually on the listview at runtime:

string user = Environment.UserName; //String that holds the current logged in user name
        string appdata = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); //string that holds the users app data path
        string docpath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); //string that holds the users My docs path
        string size;
        public Backup_test()
        {
            InitializeComponent();
            listView1.Dock = DockStyle.Fill;
            listView1.View = View.Details;
            listView1.CheckBoxes = true;
            listView1.BackColor = System.Drawing.Color.LightGray;

            listView1.Columns.Add("Name", 200, HorizontalAlignment.Left);
            listView1.Columns.Add("Location", 300, HorizontalAlignment.Left);
            listView1.Columns.Add("Size", 120, HorizontalAlignment.Left);

           

            ListViewItem network = new ListViewItem("Mapped Network Drives");
            ListViewItem.ListViewSubItem netreg = new ListViewItem.ListViewSubItem(network, "HKEY_CURRENT_USER\\Network");
            network.SubItems.Add(netreg);
            listView1.Items.Add(network);

            ListViewItem printers = new ListViewItem("Connected Network Printers");
            ListViewItem.ListViewSubItem printreg = new ListViewItem.ListViewSubItem(printers, "HKEY_CURRENT_USER\\Printers");
            printers.SubItems.Add(printreg);
            listView1.Items.Add(printers);

            switch (Directory.Exists(docpath))
            {
                case true:
                    ListViewItem documents = new ListViewItem("My Documents");

                    size = Convert.ToString(GetTotalSize(docpath));
                    ListViewItem.ListViewSubItem docsmb = new ListViewItem.ListViewSubItem(documents, docpath);
                    ListViewItem.ListViewSubItem docsizemb = new ListViewItem.ListViewSubItem(documents, size);
                    documents.SubItems.Add(docsmb);
                    documents.SubItems.Add(docsizemb);
                    listView1.Items.Add(documents);
                    break;
            }
        }
        //
        //The following two methods "GetFileSize and GetTotalSize " orginal code was taken from:
        //http://www.dreamincode.net/code/snippet2690.htm
        //
        //

        //variable to hold the final value
        private static double totalSize = 0;


        ///

        /// method to increment our total size for the directory
        ///

        ///
        private static void GetFileSize(string path)
        {
            //get the file info for this file
            FileInfo fi = new FileInfo(path);
            //increment the total size
            totalSize += fi.Length;

        }

        ///

        /// method for getting the total size of files in a given directory
        /// along with it's sub-directories
        ///

        ///
        ///
        public static double GetTotalSize(string directory)
        {
           
            //get all files in the main directory
            string[] files = Directory.GetFiles(directory);
            //loop through all the files found
            foreach (string file in files)
            {
                //add up the size of each file
                GetFileSize(file);
            }

            //now get all the sub-directories in this directory
            string[] subDirs = Directory.GetDirectories(directory);
            //loop through each of the sub-directories
            foreach (string dir in subDirs)
            {
                try
                {
                    //use recursion, call itself to increase the size
                    GetTotalSize(dir);
                }
                catch (UnauthorizedAccessException ex)
                {
                    Console.WriteLine(ex.ToString());
                }
            }
            return totalSize / Math.Pow(1024, 2) ;

        }

That seems to be interesting..

Yes. It is possible to get the user special folders using: Environment.GetFolderPath() method
