Finding duplicates....is it all of them or X-1 ?

[Mozzer2000]

I have tried to figure this out however my 20k+ photos are a mess due to some unintended duplicate uploads and update/creation date f**k ups.

My question is that when it finds duplicates does it put all of them in the album or all but one? ie if I deleted all the photos in the dupe album am I left with one copy or do I lose all of them?

I'm assuming it puts all of them in and I go through the album and delete X-1 of the duplicates but it would be quicker if it was X-1 ( for me with so many ).

Related question is whether the size of the image counts towards the duplicate - many years ago I had a phone that took the same photo at three resolutions simulatanously. They're all in my Google account. They look the same until you inspect the resolution. Would they appear as duplicates?

Thanks- awesome tool. Really really good. Will send coffee money shortly.

It generates a hash for each item, then compares them. If hashes match within a threshold, it groups them all together.

I'm assuming it puts all of them in and I go through the album and delete X-1 of the duplicates but it would be quicker if it was X-1 ( for me with so many ).

The reason it is not "x-1" is the imperfect matching. There could be false positives and negatives.

No, it's purely thumbnail based

Thanks for the responses - I don't fully understand the final answer though. The thumbnail for an identical image at 3 different resolutions would surely be the same, therefore the hash would be identical for each resolution. Therefore all three would look to be duplicates? Or am I confused?

it depends.
Just test it on a small batch of test images
