To give visuals for anyone about to get this and run it, and let it dump what IT is convinced needs to be dumped, I got the thing again, ran it, and made a couple of screenies.
This time it found what It decided were just under 1K JUNK FILES.......Corky is right: no backup the registry option at all; it just DECIDES FOR YOU, and, again, I often put pics different places, so, while technically, they may be dups, actually, they are anything but. I do things purposefully to suit my needs.
There is no option to configure anything important!
Sorry, guys, this is a Fascistic, insensitive, arrogant, not safe, badly written app, and no way would I let it remove diddly, go along with what IT "decides".....or keep it in this system.
I will now uninstall this new one.
