Remove dash

My file names and titles are the same. They are 01-01, 01-02, 01-02, etc. I need to remove the dash so my music player will sort them correctly, not 01-01, 010-01,010-02, etc.

I know this must have been answered many times before. I just can't find an example.

If you only want to remove the -
then use an action of the type "Replace" for TITLE
Search string:-
Replace string:
(leave emtpy)
then rewrite the filename with the function Convert>Tag-Filename:
Format string: %title%
