When renaming file or folder, it does not correctly highlight the name, it stops at the first dot "." in the name, it looks like NC can't properly detect the extensions.

I can't reproduce it locally - could you provide more information?
Specific steps would be great.

Yes, no problem. E.g. create folder "folder.1.name this is folder" and when trying to rename the folder, it will only select the part "folder.1" and the rest is not highlighted:) Image in the attachment:)

That's the intended behaviour - NC decomposed "folder.1.name this is folder" as filename="folder.1" and extension="name this is folder".
Upon renaming NC highlights filenames without extensions since usually they aren't changed.

Thank you for the information, but I don't understand Folders does not have extensions, since it's folder, at least in my understanding, so it's really confusing for me. Would it be possible to have an option in the Preferences to always select the whole file name including extension, for example? That might help in this case

Well that is incorrect - directories absolutely can have extensions and MacOS uses them a lot.
".app" is the most prominent example, see https://en.wikipedia.org/wiki/Bundle_(macOS).

Thank you, every day I learn something new
