Using SSH to delete a movie transfered to ATV

I used Cyberduck to transfer several VIDEO_TS folders to the Movies Folder on my ATV. Unfortunately, after seeing the movies there’s one that I can’t delete with Cyberduck. I get an error message saying the folder isn’t empty (see attached if interested).

The Cyberduck tech support person wrote:
This is the FTP server which does not allow to delete this file and hence
because the folder is not empty it cannot be removed. You have to login to
this server using e.g. SSH to forcefully remove this file. Report this bug
to the PureFTPd server vendor.

Can anyone tell me the terminal commands to delete this folder?
Thanks,

John

You may try deleting the files inside the folder before removing the entire folder itself.
