Find & Delete Duplicates in Microsoft OneDrive

Due to the fact that Google placed extreme limitations on how storage, I opted to purchase subscription to Microsoft office 365 and OneDrive. using a really awesome app I was able to zap all the photos from Google photos over to OneDrive in a heartbeat. One problem exists however. There are many many duplicate photos and videos within my OneDrive and I have spent hours now downloading various programs on my PC to try and scan the duplicates and delete them.

There are well over 12,000 photos and videos in 46 GB of space.

The programs I have downloaded to accomplish the task are not successful. Right now I'm downloading all the OneDrive files to a zip file and I plan on opening up them in my PC and scanning the duplicates from there.

Does anybody have an easier way?

Thank you, in advance
