Files etc not moving for hearing (10)
I believe the answer is:
stationery
'files etc' is the definition.
(I've seen this before)
'not moving for hearing' is the wordplay.
'not moving' becomes 'stationary' (I've seen this before).
'for hearing' indicates a 'sounds like' (homophone) clue.
'stationary' is a homophone of 'STATIONERY'.
(Other definitions for stationery that I've seen before include "The papers, etc" , "Writing material" , "Various items in paper" , "Writer's needs" , "Writing paper, etc" .)
