Convert > Filename ..Tag

I want to cut a few characters in from of the filename when converting Filename >Tag

Example :

Filename : 01-My Song Name

Tag result wanted : My Song Name

Thanks..

Sill a newbie on this software

Use
%dummy%-%title%
The function Convert>Filename-Tag does not modify the filename.

If you have not got all the data in your tags, you could also retrieve the track number from the filename:
%track%-%title%
