If your Duplicate photos are spread across many Folders -
Search the entire computer for all images of a particular format, I.e. Jpeg ect
Change the view settings so you can see a thumbnail of the pictures
Manually identify which photos are duplicates, and then delete.
If your Duplicate photos are contained within One folder-
Sort by date/time taken then Identify which images were taken at exactly the same time, confirm they are duplicates and then delete.
I have duplicate photos. It is a well known fact that photos duplicate spontaniously on computers.
sometimes I have accidently taken more than one shot of a subject. Sometimes uploading them from a device has created additional copies. sometimes apps have created copies in folders I don't know about.
Sometimes it is good to have copies (in the cloud or elsewhere) but you don't want loads of copies.
I'll bet you have duplicates you didn't even know existed?

I'm using a free bit of software to check what has built up since I last checked a couple of years ago. Its amazing what has multiplied and not just photos. I've got quite a few duplicates of MP3s and other types of documents.
It all creeps up on you. I just wish that I was as fastidious as a some on this site, at keeping total control of their data.
> I automatically prefix all image on import with a YYMM (in LR) to prevent the latter and help with file ID and sorting.
Useful little tip.
Don't worry, the software I use does not compare file names but rather the file/image itself. The exact same images can have different names or every single image can have the exact same name yet it will spot the duplicates.
