Not sure if this works for you but I didnt see it mentioned. I use plex for my media server, so I would just put whatever it is on there and then someone else can log in remotely and download it through the app on their mobile, and I think also via the website too.

I know this works if the person is downloading from android but haven’t tested otherwise.

Okay can you explain why thats a sarcastic answer? Is one of those first three steps way harder than I think it is?

You can upgrade to satisfactory now! Its like factorio all growed up!
