In this tutorial, we will guide you through the process of uploading an existing save to your Astroneer server.

You may also refer to this guide on how to upload files to your game server.

Danger

This guide is only for Steam (PC) saves. Save uploads are not possible from console. PC Game Pass save transfers require the use of third-party tools (such as AstroSaveConverter) to extract and convert your save data to Steam.

This will delete or overwrite any progress you have made on the server.

Locating Your Local Astroneer Save File

1
On your keyboard, press Windows Key + R and enter this:
%localappdata%\Astro\Saved\SaveGames
2

Find the save you want to upload. Save files are named in the format SAVE_1$2025.01.25-09.55.29.savegame.
3

Take note of the part of the name before the $ (in this example, SAVE_1). You will need it later.

For example:

AppData

Local

Astro

Saved

SaveGames

SAVE_1$2025.01.25-09.55.29.savegameYour save file

Uploading Your Astroneer Save to Your Server

1

Log in to Bropanel and Stop your server.
2

In the sidebar, go to Files.
3

Navigate to the Astro/Saved/SaveGames folder, creating it if it does not exist.
4

Delete any existing save file, then upload your .savegame file.
5

Navigate to the Astro/Saved/Config/WindowsServer folder and open AstroServerSettings.ini.
6
Set ActiveSaveFileDescriptiveName to match the name of your save. This is the part of the file name before the $.

For a save named SAVE_1$2025.01.25-09.55.29.savegame, you would set:
ActiveSaveFileDescriptiveName=SAVE_1
7

Save the file, then Start your server.

For example:

Saved

SAVE_1$2025.01.25-09.55.29.savegameYour uploaded save file

Config

AstroServerSettings.iniSet ActiveSaveFileDescriptiveName here

Note

ActiveSaveFileDescriptiveName must exactly match your uploaded save's name (the part before the $) for the save to load.
