Free duplicate file finder

[Mimen]

I have tried several dree duplicate file finders, most of them useless regardless of me tuning the settings. Would anyone know of one for Widows 10?
I have tried
Duplicate cleaner pro - Works like a charm but Im not paying R600 for it. My antivirus was cheaper.
Duplicate file finder
Fast duplicate file finder.

If it's images, VisiPics. Else try CCleaner or HD Cleaner?

I've used Dupeguru with great success! Very nice!

Being the l44t h4ck3r I am, I used the Google Drive app to make local copies of my files, then compared the Google Drive local copies to all other files on my PC. So this way I also removed duplicates in my cloud backup (GDrive).

Iobit advanced system care has an awesome toolbox of tools that you can use to clean up your file system.

I second Merlin's suggestion of CCleaner.
