List specific directories in a listview

Question

Hello. I'm still kind of new to C# so I don't know if this is a newbie question or not. I am making a small application for backing up people data. I want to list only certain directories in a listview(ie. my documents, outlook folder, folders like that). I can enter all the folders manually at runtime into the list view and it works. I was just wondering is there a way to maybe loop through the user's profile folder and automatically list these folders in a list view instead of inserting them all manually? I hope I explained that well enough.

Thanks in advance.

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
