How do I access the Home Assistant file structure?

I’m running HAOS on a standalone PC, booting form the local disc.

I’m trying to create an automation to take snapshots from my ONVIF CCTV under set conditions and email them to a specific email address.

I have the email integration largely wrapped up but the snapshots aren’t coming through and I’m not sure that they’re even being taken. Is there any way that I can access the file structure so that I can confirm that they are being saved, or saved using the naming format that I think I’m using?

You can install the Samba add-on in Settings → Add-Ons, this allows you to connect to the folders from another computer just like any file share. You can also install SSH Terminal here if you prefer to telnet to HA.
