I want to use Mp3tag to automatically change the file name according to the track number.

Currently, I use the Tag-\>Filename tool in this manner:  
%artist% - %album% - $num(%track%,2)-14  
but first changing the last number, in this case 14, to the maximum number of tracks in the sequence.

Is there a way I can simply interrogate the Track Seq for the largest value, and use it in the formula - sort of like a $max(%track%) ?

%\_total\_files% returns the number of currently selected files.

You must click on "My Controls" and on the bottom left side there is "Change email address"  
Or just click this [link](http://forums.mp3tag.de/index.php?act=UserCP&CODE=08)
