3rd party de-duplicate

I would like to delete the copious numbers of duplicates that I have on a couple of computers prior to installing Mylio. If anyone has had success with a third party program for this task for PC, I would love to hear about your experience. Thanks

Hello, I have used Visipics and it works decently well. The main limits for me is that it doesn’t work on videos, and it failed to detect some near-duplicates when they had different resolutions (e.g. scaled-down version created by WhatsApp). But otherwise pretty good.

I’m curious to hear about alternatives too.
