Thank you Pete_UK and Mr. Ron Coderre. Your solution was simple. I
will start my folders with 01, 02, 03, etc. I will never have more
than 99 folders. And if I by chance I do, then I will renumber 01--
to 001--, 02-- to 002--, etc.

The solution was obvious to you both and I feel foolish for asking.
But I am very grateful because this will make things work for me.
Thank you again.
