Alternatively, you can use my Dynamic Renamer with the command:
-sn -/.*/{parent2} ({parent1}) - Filelist.ifl/ -/\[\d+\]\s*//g
This does the following:
-
removes the suffix
-sn -
replaces the entire filename with your desired file name, appending the parent dirs like you want
-/.*/{parent2} ({parent1}) - Filelist.ifl/ -
removes the bracketed digits including the brackets
-/[\d+]\s*//g
