File a reputation (6)
I believe the answer is:
record
I believe this clue is a double definition.
'file' is the first definition.
(I know that file is a more specific form of the action register)
'a reputation' is the second definition.

(Other definitions for record that I've seen before include "Set down in writing" , "Archives, register" , "A minute" , "It may get broken" , "Chronicle or log" .)
