ICOtec has located a freeware program that we recommend for renumbering files in your ICOtec sound library. This software allows you to open your sound library folder and move files up or down in your list. As you move the file to a new position, it will automatically renumber the order. One important thing to note, you must have a 3 digit number at the beginning of the file name, this program cannot automatically add them. You can use any three numbers; 999, 000 or whatever you wish. As you move that file to where you want.
