How to convert name to tag?

Support
1

I have songs with no tag and names e.g.

01 Queen - Bohemian Rhapsody 1975.mp3

I try: %track% %artist% - %title% %year%

but year is "Rhapsody 1975"

how to get year at the end to %year% ?

You can't, unless you insert another delimiter by using a RegEx replace action.

Action #1:
Action type: Replace with regular expression
Field: _FILENAME
Regular expression: (\d{4}.mp3)$
Replace matches with: - $1

[ ] case-sensitive comparison

(added file extension)
