Great, so you just need to figure out how to get files onto the Windows server from your phone.
Start by setting it up so you can access the server from your phone while you’re on your home network, then get it to work while you’re out and about.
For step 1, I use CX File Explorer app on my phone, which allows you to add network drives.
For step 2, I use Tailscale. I installed it on my server and on my phone. When I toggle it on on my phone, it makes a tunnel right to the server, so then I can open CX File Explorer and move files over.
The short answer is yes, definitely. The longer answer about how depends on a ton of details about your setup.
Let’s start with, where are the rest of the files that are in your Plex library saved? (E.g. on a Windows laptop, on a linux server, etc)
a Windows server, made of a Dell Optiplex something or other and some external hard drives.
