Is there a quick way to edit year

hi,

i am trying to edit 600k files where the date is set out like this 1985-11-11, however is there an action to delete the other part and just leave the year (1985-11-11 would be 1985 instead)

Try Convert>Tag-Tag or an action of the type "Format value" for YEAR
Format string: $num(%year%,1)

Thank you, it has worked
