Here's my code to recursively delete foldersand theirfiles/subfolders from the isolated storage. It works on Windows Phone 8, too.

public static void CleanAndDeleteDirectoryRecursive(string directory)
    {
        IsolatedStorageFile iso = IsolatedStorageFile.GetUserStoreForApplication();
        if (iso.DirectoryExists(directory))
        {
            string[] files = iso.GetFileNames(directory + @"/*");
            foreach (string file in files)
            {
                iso.DeleteFile(directory + @"/" + file);
                Debug.WriteLine("Deleted file: " + directory + @"/" + file);
            }

            string[] subDirectories = iso.GetDirectoryNames(directory + @"/*");
            foreach (string subDirectory in subDirectories)
            {
                CleanAndDeleteDirectoryRecursive(directory + @"/" + subDirectory);
            }

            iso.DeleteDirectory(directory);
            Debug.WriteLine("Deleted directory: " + directory);
        }
    }
