Whow! Here is the copy from:

# 
https://stackoverflow.com/questions/48757748/removing-orphaned-sidecar-files-by-extensionRun
#
shopt -s nullglob extglob;

# Get all sidecar files
for file in *.{xmp,pts,pp3}
do
   # Generate all permutations of filenames that it may belong to,
   # and let globbing delete the ones that don't exist
   candidates=("${file%.*}"@() "${file%.*}".{nef,raf,orf}@());

   # If none exist, the file can be deleted
   [[ ${#candidates[@]} -eq 0 ]] && echo rm "$file"
done
#
# --------------------

  I'll test it later with "mv" instead of "rm"

Thanks
