async Task<StorageFolder> GetStorageFolderAsync(User user, string path) {     
    // It is possible the folder no longer exists     
    // or permissions were changed so that the     
    // app no longer has access to the path.     
    try     
    {         
        return await StorageFolder.GetFolderFromPathForUserAsync(user, path);     
    }     
    catch( System.IO.IOException ex )    
    {         
        // File, or path not found I/O Exceptions can happen  
        // notify user or implement fallback, etc...         
        string message = ex.Message;
