Set of documents (7)
I believe the answer is:
dossier
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">set of documents</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for dossier that I've seen before include "File of papers (sometimes dodgy)" , "File of documents" , "Papers containing detailed information about a particular person" , "Report" , "Record" .)
