I am trying to renumber my MP3s so they all have two digits. If I short by track number, I end up with:

01  
01  
01  
1  
01  
1  
01  
01  
1

Is it possible to sort this so all the 1's and all the 01's are grouped. This would make my life so much easier for renaming.

I don't want to select all and rename because it will force me to copy far more files to my backup/NAS than required.

Thanks

You can use the filter [F3] to display only track numbers with one digit:

track MATCHES ^\d$

Or you could create a userdefined column with the value of  
$len(%track%)  
and sort first by this and then by track.
