Have looked through support pages but still can't figure out the problem with leading zero's
Tracks number correctly if only up to 99 in file but say 103 tracks and window displays duplicate 8 or 9 numbers etc
believe this is a old problem with explorer is there a way around this
At present I number tracks 1 to 80 with auto number no leading zero then select 81 onwards so as display continues with the leading zero and # gives proper track number in Explorer

> 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.
