Has anyone experience with this tool from PCTools Software? I am
running W2000 pro workstation and would like to clean things up a bit if
there is minimul risk in the attempt. In past decades I would just go
into the file and clean it myself but things have become more
complicated over the years and I have been busy with other things so
have lost my edge of knowledge.
