Auto delete Dahua NVR

[Turks]

Hi guys. I have a client with a NVR1B04HS-4P NVR, I would like for the camera to only record 14 days worth of footage and then overwrite. Can someone let me know how I can accomplish this. Thanks

This is how i set it. Can someone confirm if this will only record 14 days of footage? And when it deletes something which file will it delete? I assume the oldest file?
