Name a file afresh (5)
I believe the answer is:
alfie
'name' is the definition.
'a file afresh' is the wordplay.
'afresh' is an anagram indicator.
'file' anagrammed gives 'lfie'.
'a'+'lfie'='ALFIE'
(Other definitions for alfie that I've seen before include "Michael Caine role reprised by Jude Law" , "Boy" , "Name of fellow" , "1966 Michael Caine film" , "well-known film" .)
