The filename is not so well formed to allow Mp3tag to guess how to fill the fitting tag fields.
As a first step you may reformat the filename by a regular expression like you find it in the following proposal and then let Mp3tag guess the values.
Action #1 Actiontype 7: Import tag fields (guess values) Source format: $regexp(%_filename%,'^(\d+)÷(.+)÷(.+?)÷featuring÷(.+?)$','$1÷-÷$2÷-÷$3÷-÷$4') Guessing pattern: %TRACK%÷-÷%TITLE%÷-÷%ARTIST%÷-÷%FEATURING% Note: Replace each special ÷ character with one space character.
This is rather tricky and does not work in all cases but with filenames havin the same word structure like the example filename.
Where does the track number come from though? Are you doing Filename to tag, and there's a dot in the filename? If that's the case then you just need to add a . to the formatting string after the track number. Need more more information to give a more specific answer.
If you just want to remove the . from existing TRACK fields, make a Replace action that searches the TRACK field and replace . with nothing.
