> Greetings, I have a large folder of songs. I run auto numbering wizard and then convert tag to file name. Both operations are successful but when i look in windows explorer i have files with duplicate numbers. I have deleted and nw lost a whole number of files trying to get this to work. Please can someone help me?

I doubt that there is another way around it than to save numbers that they do not have leading zeros when there are 3 digits.
