Abiotic Factor Save File Location

Last verified: 2026-10-01

Save file location (Windows (Steam)): %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames

Quick answer: On PC, Abiotic Factor stores your worlds under %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames (full path C:\Users\<you>\AppData\Local\AbioticFactor\Saved\SaveGames). This is the standard Unreal Engine Saved location, NOT Documents and NOT the Steam install folder. Each world is its own folder of .sav files. In co-op, only the HOST keeps the world here — joining players have nothing to copy; to move a co-op world you must take the host's SaveGames folder. The quickest way in is the game's own 'Open Save Folder' button on the load screen. AppData is hidden by default, so enable 'Show hidden files' or paste the %LOCALAPPDATA% path directly. Steam Cloud mirrors solo saves, so a corrupted world can propagate — copy the folder before verifying files.

Abiotic Factor is an Unreal Engine game, so your solo and hosted co-op worlds are not in Documents or the install folder — they sit in the hidden AppData\Local tree. The host of a co-op game holds the only real copy of that world. Here is exactly where to look, how to use the in-game Open Save Folder button, and how to back up a world before it corrupts.

Save file locations

Windows (Steam)
%LOCALAPPDATA%\AbioticFactor\Saved\SaveGames

Full default: C:\Users\<you>\AppData\Local\AbioticFactor\Saved\SaveGames . Paste %LOCALAPPDATA% into the Explorer address bar, then open AbioticFactor\Saved\SaveGames. Each world is a subfolder of .sav files.

In-game shortcut
Load screen > Open Save Folder

On the load/continue screen, select a world and click 'Open Save Folder' to jump straight to that save in Explorer without typing any path — the safest way to find the exact folder.

Co-op (dedicated / hosted server)
Server install: AbioticFactor\Saved\SaveGames (server machine)

On a dedicated or hosted server the world lives in the server's SaveGames folder, not on any client. To migrate a co-op world, copy the world folder from the host/server, not from a joining player.

Alternate (older/edge installs)
%LOCALAPPDATA%\..\LocalLow\Deep Field Games\Abiotic Factor

A few setups report a LocalLow path under the publisher name. If SaveGames is empty under AppData\Local, check the LocalLow tree before assuming the save is lost.

Cloud saves

Abiotic Factor uses Steam Cloud for solo worlds. It uploads automatically, so a corrupted or half-written world can overwrite your good cloud copy the next time you launch, with no visible version history. Hosted co-op worlds are NOT in your cloud — the host machine holds them. Treat a manual copy of the SaveGames folder (or the host's) as your real backup.

Cloud save conflict & platform recovery

The common loss is 'my co-op world is gone' or 'solo progress rolled back' — in co-op the joining player never had the world, and in solo a Steam Cloud sync overwrote the good local copy after a crash.

  1. Before relaunching after a crash, copy %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames somewhere outside the game folder.
  2. For co-op, remember the HOST holds the world — copy the host's SaveGames folder, not a client's, to back up or migrate it.
  3. If Steam Cloud rolled back a solo world, go offline, restore your copied world folder, launch once offline so the game reads it, then reconnect so the good save uploads.
Back up first (Windows) — copy & run

FAQ

Where is the Abiotic Factor save on PC?

In %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames (C:\Users\<you>\AppData\Local\AbioticFactor\Saved\SaveGames), the standard Unreal Engine location — not Documents and not the install folder.

How do I open the Abiotic Factor save folder quickly?

On the load screen select a world and click 'Open Save Folder', or paste %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames into Explorer's address bar.

Where is my co-op world saved in Abiotic Factor?

On the HOST (or dedicated server) machine, in that machine's SaveGames folder. Joining players do not keep the world locally, so to migrate a co-op game you copy the host's save.

Does Abiotic Factor use cloud saves?

Yes, Steam Cloud for solo worlds. It auto-uploads, so a corrupted world can overwrite your good cloud copy — copy the SaveGames folder manually before verifying files. Co-op worlds are not in your cloud.

Why did my Abiotic Factor progress reset?

Usually a Steam Cloud conflict after a crash: the older save won the sync. Restore your backup with cloud disabled, launch once, then re-enable cloud. For co-op, make sure you are checking the host machine.
