Where Are Abiotic Factor Save Files Located?
Where Abiotic Factor keeps its co-op world saves per Steam ID on PC, plus dedicated server worlds.
Last updated
Abiotic Factor saves worlds at %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames\<SteamID>\Worlds on Steam. The numeric folder is the Steam account ID, and dedicated servers use a Server branch instead.
The in game Load screen has an Open Save Folder button, which beats every typed path in this post. Copy the Worlds folder with the game closed to migrate or share hosting. Game Pass builds use different roots, so confirm the button's destination before assuming Steam paths. Host moves need Worlds, not profiles.
Where Abiotic Factor stores this, by platform
%LOCALAPPDATA%\AbioticFactor\Saved\SaveGames
Worlds/ per Steam ID folder; Server/Worlds for dedicated hosts. Use the Load screen button to open it directly. Config sits beside saves under Saved/Config/WindowsNoEditor for graphics tweaks.
~/.local/share/Steam/steamapps/compatdata/427410/pfx/.../AbioticFactor/Saved/SaveGames
Same Steam ID nested tree inside the Proton prefix. Copy the Worlds folder across with matching IDs. Dedicated Linux servers follow the Server branch layout identically.
Frequently asked questions
how do i back up abiotic factor worlds
Copy %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames\<SteamID>\Worlds to the same path on the new PC with the game closed. The numeric folder binds saves to the account. The Load screen offers an Open Save Folder button that skips typing entirely.
where are abiotic factor dedicated server saves
Under SaveGames\Server\Worlds in the same tree (dedicated) rather than the Steam ID folder. Copy the Server branch for host migrations, not the personal one. Server config travels separately from the world files.
does abiotic factor use steam cloud
Yes through Steam Cloud for the personal Worlds folder, with Game Pass paths differing. Co-op guests need the host's world files to take over hosting; syncing tools like SaveSync automate the handoff. Confirm the live path in game before copying.
