Can't find mnt Folder | URGENT

Hello all

i followed all the instructions found on the forum and support pages. I’m able to connect to my apple tv (black) trough sftp, but i cant find the mnt folder where the movies and images are stored. Did apple change anything on the file structure?

I attached a screenshot how my filestructure looks.

I’m using the latest tethered firmware version.

Thank you for your help!
