XnView Software

looks good, thanks!

See the hyperlinked text "this directory" in my original post.

"FInd similar files" is unreliable when examining photos converted from HEIC to JPG

Effect: duplicate photos are not identified.

To reproduce:
1. Open this directory in XnView MP.
2. Click on "Tools" - "Find similar files".
3. Select "Similar image content".
4. Set similarity to 60%.
5. Click "OK ...

The identification of duplicates is corrected in 1.9.0. However, the misidentification of non-duplicates remains.
Specifically, with a threshold of 60%, XnViewMP 1.9.0 identifies P1000017.JPG and 2009-10 Mediterranean Cruise 908.jpg as a 46% match, but only with the option "between folders only", as ...

Based on https://giannirosato.com/blog/post/jpegli/ it seems that JPEGLI is the best encoder to use, but what about the other settings, e.g. DCT Method, Subsampling, etc.
Any advice is welcome!

FInd similar files is unreliable when the option "Between folders only" is selected.

Effect: non-duplicates are erroneously marked as 100% identical, which can lead to their accidental deletion.

To reproduce:
1. Open this directory in XnView ...

I find XnView's "Find similar" function very useful, but I sometimes give it too big of an assignment. If I change my mind and try to Cancel the operation, XnView MP generally doesn't respond to the Cancel button. This often leaves me no other choice but to force a hard shutdown, by holding down the ...

Sorry, my bad. In XnView MP 1.8.2 it's at the top of the first ("Caption") tab of the "Edit IPTC" dialog (Ctrl-I in "View" mode). The field name is "Document title".

I found it at the bottom of the first pane. YMMV.

@Gerald,
I am using all 3 of these options, and would settle for any of them in the "Find similar files" results view.
However, what I had in mind when I made the suggestion was the "Labels" from the "Thumbnail" settings.
This is also what I most often refer to.

I take way too many pictures and make too many backups. XnView MP's "similar files" feature saves me a lot of time cleaning out similar and duplicate pictures. However, there is one feature I am missing. The results view helps me to compare the pictures, but I often have copies of the same picture ...

Perfect, thanks!

@user0
Thanks, that created the file.

@Kadet,
That doesn't work for me (in XnViewMP 1.80). I see no change in the drop-down menu for aspect ratios when a selection is active in the picture and no "specific ratio". There is an entry "fixed ratio", but it doesn't seem to do anything.

As it turns out, XnView MP handles this automatically in most cases. If I select 16:9 and attempt to make a crop selection on a portrait mode picture, XnView MP automatically uses 9:16 instead. However, there are still cases where this does not suffice, e.g. when I want to crop a portrait mode ...

Thanks, but I don't find any such file. Where is it located?

P.S. A search my installation directory, c:\Program Files\XnViewMP, finds no XML files at all.
Searching the entire PC for cropsize.xml or CropSize.xml comes up empty.
