There are good reasons for duplicate copies of files on a system.
Any program installed may install a duplicate of a file that a different program uses. If that file is not in the location in which that program placed it, it's highly unlikely that the program will have the capability to search the entire system, looking for the expected file.
A user removing duplicate files that are anything other than duplicates of data files...is asking for trouble, IMO.
I have tons of duplicate files...but they are all music or graphics or video files which I have created intentionally.
A partition/hard drive may possibly become too full...but removing duplicate files needed by programs...isn't the solution to that.
FWIW: I believe that freeware list is not meant to be an endorsement of any of those programs, it's merely provided as a courtesy for members who are looking for a given type of program.
