Only remaining questions.using using Square brackets to find a match it also adds the search itdm to the output
e.g.
[$track$] if positive it ads Track to the output
Is there a way to perform this search without adding Track to the output, sorry I'm not using the correct terminology, but hope I'm getting across what I mean 
Maybe ($Track$) would achieve this 
Thanks everyone for all the help and advice
No, TBH I don't understand a word.
What does
what is "zxwsy"? What search?
Was a typo
Corrected it now
Wondered if %track% - ]%artist% - %title%
Is it possible to do the search where 'Track' is not sent to the output, just wondered,
Renaming my 174K files as I write this, mp3tag is so powerful
Use the filter
%track% MISSING
Just found a problem with
track% - ]%artist% - %title%
ACTION
if the tracks are numbered
1/11
2/11
3/11
The track numbering in the file name isn't good
Need to use the first number of the track
e.g.1,2,3 etc
Is this possible to add to the action
Also use a two digit number system
i e.
01,02,03 etc
Thanks in advance
Instead of the plain %track% use $num(%track%,2)
