Delete Filename Based On Current Folder


I am trying to rename my song filenames from the current format "Artist - Folder - Track Number - Track Title" to just "Track Number - Track Title"

e.g. "Anathema - 05. Eternity - 01 - Sentient (Instrumental).mp3" to "01 - Sentient (Instrumental).mp3"

I have tried variations of the following command, however they don't seem to work.

Replace "_FILENAME": %_directory%" -> ""

Could anyone help me out with this?

Also due to an error earlier on (that cannot be undone by Ctrl-Z) the filenames also have the tracknumber in front of them. Is it possible to delete the first 3 characters of a filename only?

Thank you in advance.

You could use "Convert > Filename - Filename" with
mask old filename:
%1 - %2 - %3 - %4
mask new filename:
%3 - %4


Thank you very much for your help, I found out how to remove the track numbers before your reply with a program called Total Commander, however by changing the mask filename like you suggested fixed this also, so it fixed two problems in one. Once again, thanks for your help.
