xmp file extension spelling

[bildbaendiger]

I have noticed that in PM6 the spelling of the xmp extension has changed from lower case (.xmp) to upper case (.XMP). I can track the change to 2022 in my database.
Is there a reason for this change?
The problem is that other programs such as Affinity or XnView only read metadata from a file with a lowercase .xmp extension.
PM6 seems to read both spellings.
Is it possible to change the spelling of the ending back to lower case?

Ok, I found it:
I didn't realize that file extensions dialog also apply to sidecar file.
When I switch to "Use lower case extensions" PM6 generate sidecar files with the lowercase ending .xmp.
Thanks for the help.
