I need help understanding what the community’s recommendation is for how to save my files across two pcs without having to manually cut and paste or setting up a NAS.

My situation is that I have a Linux server running Opensuse pulling down media through an Arr stack setup. It only has .5 TB available but I have a Windows PC with 3 TB available. I would like to know if there’s a way that I can seamlessly direct my Linux server to save onto my windows PC without me having to manually copy and paste.

Let’s say I initiate a download of a .75TB file on my Linux server, can I just have it save directly to my available 3TB windows PC? And then be also able to tell an app like Jellyfin to read it from there?

Long term I was thinking that I would set up a separate NAS but I don’t want to do that for a few months. I want to stabilize my current setup before adding another machine.

Am I crazy to think that I can save files to my windows computer from my Linux server? I have tried to look into different things. I started going down the route with samba, but it seems to only show files to my windows PC but not actually save them there directly from Linux. I’ve looked into FTP/SCP but I don’t know a good guide or if would do what I need. I am struggling understanding the networking portion of this, so let me know if I am wrong.

As a secondary question, if I had a NAS, could I also point some of that free 3TB from the windows pc to be used as part of the NAS?

Edit: I struggled a lot with this and ultimately got scared away from it for the connectivity reasons mentioned below. I ended up figuring out how to mount an external drive using fstab. This should meet my short term goals. Thanks all!
