DT picture file name with "_o" [solved]

Hi,
Im using mac M1 ventura and darktable 4.2
What does it mean picture file name like this xxxxxxxx_o.jpg. I have two jpg files with the same beginning but different on the end.
Example from my Finder

  1. dscf0481_22191424343_o.jpg
  2. dscf0481_22191424343_o.jpg.xmp
  3. DSCF0481.JPG
  4. DSCF0481.JPG.xmp
    Both jpg files have the same picture.
    In DT database I see only files DSCF0481, without “_o”
    Is it safe to delete two files with “_o”?

Thanks for any suggestion

Have you been using flickr?
