Search dupe image only between 2 folders

[Albator V]

Hi,
What is the setting to search duplicates images between 2 folders but not inside each folders ?

Folder A
> image1.jpg
Folder B
> image1.jpg
> image1+jpg

So only display duplicate image1.jpg (Folder A and B), not image1+.jpg

In your example it will always show image1 and image1+ (Folder B) because they both match something in folder A.

You can ignore duplicate groups which are entirely in the same folder using:
"Ignore duplicate groups within the same folder" (More duplicate options)
