Flies off to get folders (5)
I believe the answer is:
files
'folders' is the definition.
(I've seen this before)
'flies off' is the wordplay.
'off' indicates an anagram.
'flies' with letters rearranged gives 'FILES'.
'to get' acts as a link.
(Other definitions for files that I've seen before include "Archival records" , "Tools for documents holders" , "Folders holding documents" , "Tools to cut metal or paper containers" , "Folders in which papers are held, or tools to cut metal" .)
