How to delete all files and folders (with files) in IsolatedStorage.

Question

Hi awesome programmer:-) The code I have to clean up the local folder doesn't work properly so I won't even bother posting it here. I basically want to have a "master reset" option to remove all new created files and folder in the local folder.
Can you give me simple code to remove all files/folder so the app goes back to the state it was when the user installed it for the first time? Thanks in advance. ps I were able to delete a directory(-ies) with this method:
private async void DeleteDirectory(string directoryName)
try
var folder = await Windows.Storage.ApplicationData.Current.LocalFolder.GetFolderAsync(directoryName);
if (folder != null)
await folder.DeleteAsync();
this.Dispatcher.BeginInvoke(delegate()
txtUpdateFeed.Text = "Folder < " + directoryName + " > deleted.";
catch (Exception ex)
this.Dispatcher.BeginInvoke(delegate()
txtUpdateFeed.Text = "Delete Directory << " + directoryName + " >> Error: " + ex.GetBaseException().Message.ToString();
It seems to work, I have not tested with all conditions though. Anyway let me put up the code so you can see I have been trying: This is to delete everything but not all files are deleted:
private void WipeAllData(bool bln)
try
txtUpdateFeed.Text = "Removing files...";
if (bln)
txtUpdateFeed.Text = "Removing folders...";
//Delete videos directory
DeleteDirectory("videos");
//Delete pictures directory
DeleteDirectory("pictures");
txtUpdateFeed.Text = "Folders removed.";
//Delete the rest of the files
var iso = IsolatedStorageFile.GetUserStoreForApplication();
foreach (string name in iso.GetFileNames())
iso.DeleteFile(name);
BtnWipeAllData.Content = "Wipe All Data";
VideoCameraPowerValue = "on";
BtnVideoCameraPower.Content = "Video Camera: ON";
PhotoCameraPowerValue = "on";
BtnPhotoCameraPower.Content = "Photo Camera: ON";
txtUpdateFeed.Text = "Files removed successfully.";
catch (Exception ex)
MessageBox.Show("Wipe All Data Error:\n" + ex.Message.ToString());
Why isn't all files being deleted?

Hi Clint William Theron,
Based on your descriptions, I know that when you run the above code, it does not delete all the files, then have you checked that which kinds of files or in which folder the files can not been deleted?
Besides, if you want to let the app go back to the state it was when the user installed it for the first time, then an easy way is to uninstall and reinstall it.
