Read, copy and paste the content of an Nikon sidecar (nksc) file

[WulfG]

Dear forum members

I am new to this forum and have the following question:

In XNView MP under “Create -> Filelist” there is the option to export EXIF and IPTC information from images to a .txt/.csv file. Unfortunately, this option does not work for “.nksc” files.

I have over 6,000 jpg images, which I have labeled with Nikon NX Studio. The information (title, description etc) can be found in the “.nksc” file (Nikon sidecar) associated with the image. I would like to extract the image descriptions from the “.nksc” file to search them i.e. for spelling mistakes.
With XnView MP I can display the content of an “.nksc” file (see att. jpg file). With a click of the right mouse button it is possible to copy the XMP information and paste it into a .txt file (for example). Unfortunately, only for one ".nksc" file at a time .

Is it possible to read, copy and paste the contents of several (e.g. a whole folder) “.nksc” files?

My software: Windows 11 Pro (Vers. 24H2); XNView MP 1.8.4 64-bit (Windows) - Libformat 7.201; Nikon NX Studio 1.7.1 64bit; DxO Photo Lab 8.2.1 Build 487

Thank you very much for your reply, Greetings Wulf

.nksc is only a XML text file like .xmp?

Hello Pierre
I hope I can explain it correctly
The image descriptions in a .nksc file are coded in binary and look something like this:

But I have found a "more or less" simple way to copy the image description from the .nksc files into the original .jpg image files in Nikon NX Studio.
As soon as I have described the procedure in detail, I will publish it here.
Many thanks and see you soon
Wulf

Please see my new post "Copy image descriptions from .nksc files into the original image file" in which I describe how to process .nksc files.
Thanks and Regards, Wulf
