Hi, really nice program is the best sure, I test maybe ALL programs in this type. Congrats!!!
Suggest new option
Convert \ Actions \ Replace \ \_FILENAME \ (new option)
only as whole word
case-sensitive comparison
only in the beginning (new option)
Example to apply
the majority of new music releases house, progressive, trance ... start with 01- 02-... and 01\_ 02\_ ..., but if the name contains 01- 02-... example "02-hakan\_ludvigson\_and\_al02-break\_it\_\_marcos\_petraza\_remix-ute"
changes to "hakan\_ludvigson\_and\_albreak\_it\_\_marcos\_petraza\_remix-ute"
Other suggest, option button to SAVE Cover Art in Tag Panel
Sorry my bad english, and thanks for you work 😉

Try a regular expression instead:
_Action type:_ **Replace with regular expressions**
_Field:_ **_FILENAME_**
_Regular expression:_ **^\d+[-]**
_Replace matches with:_
