Q: RAW codecs (.SRW)

Dear all

i am using a Fuji X100 and a Samsung NX

while the raw pictures from the x100 are working properly Photos app can't open the SRW's from Samsung, i can import them, i get a Thumbnail but doubleclicking it i get an error without a message and the RAW can't be shown, if i open it in Affinity Photo it works properly, is there any codec problem or what do i do wrong?

Thanks for your help

Mirco
