Converting Tags in Filename


I would like converting TAGS in FILENAME to make them to be like in this example:

  1. TITLE [ARTIST].mp3

However, I do not get to add [ ]. It is written in the help topics that I "have to put the single quote around these reserved characters if" I "want to use them unparsed". However, I do not get to make it to work.

May someone give me an example of a proper form?

How can I make the function to work?

I thank so much for any help!

Best wisthes,


Like '['%artist%']'

Thank you so much.
It worked in a test.
However, I did not work previously. Do you know if I have done something wrong?
Best wishes,
