I would like my filenaming to show [Catalog number] if there is that value in the folder name, otherwise leave empty.
I am currently using
$if2(%albumartist%,%artist%)/$if2($left(%originaldate%,7),%originalyear%,$left(%date%,4),0000) - %album% ($if2(%releasecountry%,XX)-$if(%date%,$left(%date%,4),0000)) $if($eq(%catalognumber%,[none]),[%catalognumber%])
/$if($gt(%totaldiscs%,1),%discnumber%,)$if($ne(%albumartist%,),$num(%tracknumber%,2) ,)$if(%_multiartist%,%artist% - ,)%title%
which results in
Group/Original YearMonth - Album (CountryCode-Release Year) [Catalog number]/Track number Track Title.mp3
Eg.
Angelus Apatrida/2021-02 - Angelus Apatrida (XW-2021)/01 Indoctrinate.mp3
which is ok as that release does not have a catalog number
Kreator/2020-02 - London Apocalypticon_ Live at The Roundhouse (DE-2020) [27361 48105]/201 Choir of the Damned.mp3
which is ok as that release has a catalog number
However, I am also getting
Alice Cooper/2021-02 - Detroit Stories (US-2021) []/01 Rock 'n' Roll.mp3
Could anyone please clarify? If Alice Cooper’s catalog number is empty, why is it printing [] when nothing should have actually be printed?
Thank you for your support in advance.
