If you and your friends have been playing Satisfactory in co-op, one of you hosting from your own PC, moving that world to a MintServers dedicated server is one of the most common requests we get. The good news is you don't need any file transfer tools, it's handled entirely through the in-game Server Manager. This guide covers finding your save, uploading it, and what changes about who's in charge once it's on a dedicated server.
Step 1: Find Your Local Save File
Your existing save lives on whichever PC was hosting the co-op session (or on your own PC if you were playing solo).
Save File Location (Windows)
%LocalAppData%\FactoryGame\Saved\SaveGames\, inside a subfolder named after your Steam or Epic ID. Each .sav file inside is a separate save.
You don't actually need to go digging through this folder for a normal upload, the in-game Server Manager reads it automatically. It's only worth knowing if you want to manually back up a save file.
Step 2: Upload It Through Manage Saves
Loading a save restarts the server. Give it a minute or two to finish before you and your friends try to connect, larger factories take a bit longer to load in.
About Session Ownership
Whoever hosted the co-op session before doesn't carry any special status over to the dedicated server. Satisfactory saves don't store per-player admin permissions, only the world itself. On a dedicated server, admin access is controlled entirely by the Admin Password set when the server was claimed, so whoever holds that password can manage settings, load saves, and access the console, regardless of who hosted the original session.
If your group wants to hand off admin duties to someone else, that's just a matter of sharing (or changing) the Admin Password rather than anything tied to the save file itself.
If you have more than one save you want available, you can upload each one separately, they'll all show up as their own session under Load Save, and you can switch between them anytime.
