Need a quality Duplicate File app to get rid of my duplicate files over the years.

Hi

I'm concious this has probably been asked many times before, but can anyone recommend

a decent / quality app to sort through and find duplicate files on my SSD and external drives.

I have been using singlemizer but not confidient it is doing a good enough good or if there are better

alternatives out there. It's more to streamline the files I have and easy to find them in spotlight rather than

for the space, but that would difinitely help.

Thanks in advance.

Matt
