Where can I find local file


I have made an playlist in Iris called radiochannels , I pressed create playlist → and then added an amount of url’s to diffrent radiochannels both from Tunein and from outside tunein,

Now I wanna have that file where the radiochannels is stored, but I cant find it on my Raspberry pi, I have checked var/lib/mopidy/m3u but that folder its empty. Someone who has an idea where I can find it ?

found it, in my music folder of course
