I had this in my Actions for a long time, but now it seems to have no effect on the TRACK field anymore.

It should convert track "1" to track "01"...

What is the right format string to use ?

Thanks !

What kind of files are these?  
e.g. MP4 do not allow leading zeros

As a side note here, while the TRACK field does not allow a leading “0”, this does not preclude you from using the “$Num(%track%,2)” function when updating directory or file names. So this is still very useful in those cases, even with the m4a format.
