Abiotic Factor stores its save files at %LOCALAPPDATA%\AbioticFactor\Saved\SaveGames on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps every version, so a corrupted or overwritten save is one click from restored.
Where Abiotic Factor saves are stored
- Windows —
%LOCALAPPDATA%\AbioticFactor\Saved\SaveGames
The save data here is .sav files — back up the folder as a set, not single files, so a restore always keeps them consistent.
How to open the save folder
- Windows — press Win+R, paste
%LOCALAPPDATA%\AbioticFactor\Saved\SaveGames, and press Enter.
Backing up Abiotic Factor saves automatically
- Install Checkpoint64 (free) and pick Abiotic Factor — the save path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click if a save corrupts, gets overwritten, or a mod breaks it.
Sharing Abiotic Factor saves with friends
Abiotic Factor has co-op, so the folder above usually lives on one person's PC — whoever hosts. When they're offline nobody else can carry on, and if two people play separately, one session quietly overwrites the other.
Checkpoint64 lets a small group pass one Abiotic Factor world around instead of renting a dedicated server. Whoever plays next takes a server-enforced lock, pulls the latest save, plays, and pushes it back; everyone else stays read-only until the lock frees up, so nobody saves over anybody. Every version is kept, so a bad session is one restore away. The dedicated server alternative guide walks through the full take-turns flow.
