Thanks ewemoa.
I dont remember seeing them in FARR before, but this could be because the files I expected to be at the top of the list here are not showing (that's not relevant here beyond making me notice these files).
I changed some folder settings a while back, maybe it's because of that (show system files I guess).
Will change that setting back to 'hide' and see.
hmm, no immediate difference. Maybe they were always in FARR ...
