Closes a successful FindFirst file search SysUtils unit
 function FindClose ( var SearchResults : TSearchRec ) : Integer;
The FindClose function closes a successful FindFirst (and FindNext) file search. It frees up the resources used by the search in SearchResults.
A FindClose call is not necessary if FindFirst finds nothing, but must be called if it does, even if a subsequent FindNext call fails.
