MyISWeb, welcome to the forum! Glad that you like CCleaner, it's one of the best (if not the best) free apps of it's kind. Finds junk that you'd never find.
Defraggler was a staple app for me for over two years. But now, I have Perfect Disk 11 Pro, a paid defragger & optimizer program.
But if you want a better one than Defraggler, that also has an optimizer with it, that's also free, Auslogics Disk Defragger is the best of the free ones that I've used. Still run it on my notebook, it defrags then optimizes your disk(s), you can schedule runs, too.
It can be found at:

Hope that you find it useful.
