// This method deletes directories in the specified Isolated Storage, after first 
// deleting the files they contain. In this example, the Archive directory is deleted. 
// There should be no other directories in this Isolated Storage.
public void DeleteDirectories()
{
    try
    {
        IsolatedStorageFile isoFile = IsolatedStorageFile.GetStore(IsolatedStorageScope.User |
            IsolatedStorageScope.Assembly |
            IsolatedStorageScope.Domain,
            typeof(System.Security.Policy.Url),
            typeof(System.Security.Policy.Url));
        String[] dirNames = isoFile.GetDirectoryNames("*");
        String[] fileNames = isoFile.GetFileNames("Archive\\*");

        // Delete all the files currently in the Archive directory.

        if (fileNames.Length > 0)
        {
            for (int i = 0; i < fileNames.Length; ++i)
            {
                // Delete the files.
                isoFile.DeleteFile("Archive\\" + fileNames[i]);
            }
            // Confirm that no files remain.
            fileNames = isoFile.GetFileNames("Archive\\*");
        }


        if (dirNames.Length > 0)
        {
            for (int i = 0; i < dirNames.Length; ++i)
            {
                // Delete the Archive directory.
            }
        }
        dirNames = isoFile.GetDirectoryNames("*");
        isoFile.Remove();
    }
    catch (Exception e)
    {
        Console.WriteLine(e.ToString());
    }
}
