Hi everyone

I'm trying to convert the folder names and file names to a new format. But I can't get it to work. Here is the current folder & filename and what I want to convert them to.

[IF][LOWER][genre][],=,classical,
     [IF][compilation],=,1,1_Classical\[album]\[IFMULTI][disc]-[][track]-[title]_[composer]_[artist]-[disc_total],
...
