Delete old Camera Snapshots

Hi,
I have a couple of Reolink Cams that store Motion Videos in

My Media/Cameras/yard/yyyy/mm/dd

I upload them via ftp because it is convenient to browse there via Phone App

My Problem is, that I tried to setup delete old files with this:

(https://github.com/chomupashchuk/delete-file-home-assistant)

But I cannot figure out how to access those folders.
what is the exact path to My Media?

Ok, got it:

It’s “/media/cameras/yard/yyy/mm/dd”
