Astroneer Save File Location

Last verified: 2026-10-08

Save file location (Windows (Steam)): %LocalAppData%\Astro\Saved\SaveGames

Quick answer: On PC (Steam), Astroneer saves live in %LocalAppData%\Astro\Saved\SaveGames. Each world is a .savegame file with a timestamp in its name. This is in the hidden AppData\Local folder, not the Steam install. The Microsoft Store / Xbox PC version stores saves separately under its own packaged AppData folder.
Windows (Steam)
%LocalAppData%\Astro\Saved\SaveGames
Windows (Microsoft Store / Xbox app)
%LocalAppData%\Packages

Here's exactly where the Steam version of Astroneer stores your worlds on PC, how to open the folder fast, and how to back up a save before an update.

Save file locations

Windows (Steam)
%LocalAppData%\Astro\Saved\SaveGames

Full path: C:\Users\<YourName>\AppData\Local\Astro\Saved\SaveGames . Worlds are .savegame files; the newest timestamp is your latest save.

Windows (Microsoft Store / Xbox app)
%LocalAppData%\Packages

The Game Pass / Microsoft Store build keeps saves inside its own Packages\SystemEra.Astroneer... folder and syncs via Xbox cloud — not the same place as the Steam build.

Cloud saves

The Steam version syncs through Steam Cloud, so worlds normally follow your account to another PC. Because each world is one .savegame file, copying that file is enough to move or back up a world manually when Cloud is off or conflicts.

How to open the save folder

  1. Press Win + R to open the Run box.
  2. Paste %LocalAppData%\Astro\Saved\SaveGames and press Enter.
  3. Sort by date and copy the newest .savegame file somewhere safe.
  4. Back up before installing an update or experimenting with a world.

Save problems & fixes

My Astroneer world is gone after an update

Check %LocalAppData%\Astro\Saved\SaveGames for older timestamped .savegame files — the game keeps several. Copy the one you want back and rename it so it loads.

Steam and Microsoft Store saves don't match

They're stored separately and don't share progress. Decide which build you're playing and copy its .savegame file; the other platform keeps its own worlds.

FAQ

Where is the Astroneer save on Steam PC?

C:\Users\<YourName>\AppData\Local\Astro\Saved\SaveGames — each world is a timestamped .savegame file.

Why can't I find the SaveGames folder?

AppData is hidden by default. Paste the path into the Run box (Win+R) instead of browsing, or enable 'Hidden items' in File Explorer.

Are Steam and Microsoft Store saves in the same place?

No. The Steam build uses %LocalAppData%\Astro; the Microsoft Store / Xbox app build keeps saves inside its own Packages folder.
