Or save straight back into the folder

The editor writes your changes into the folder itself instead of handing you a download (Chrome and Edge only; the browser asks you to allow it). Chrome and Edge never let a website change files inside AppData or Program Files, so this does not work for Steam single-player or Xbox app saves in their normal place - use the buttons above for those. It works for a dedicated server installed elsewhere (also over a network share, e.g. \\server-pc\share\…\Worlds\<world>), an Xbox XboxGames\GameSave\wgs folder, or a copy of a world.

Xbox cloud saves can undo an edit. If Abiotic Factor and the Xbox app were closed and you are offline, carry on:

1. Still offline, start Abiotic Factor, load the world, check your changes, let it save, then quit.
2. Go back online. If Xbox asks which save to keep, choose the one on this PC.

Xbox cloud saves can undo an edit. Follow every step, in this order:

1. Quit Abiotic Factor and close the Xbox app (check the system tray too). Wait a minute so the last cloud upload finishes.
2. Go offline: turn off Wi-Fi or unplug the network cable.
3. Back up the whole save folder you opened (the long-number one): copy it somewhere safe.
4. Unzip the download into that folder and let it replace containers.index. It adds a new container.<number> and data file inside one of the folders; the old ones next to them are no longer used and can stay.
5. Still offline, start Abiotic Factor, load the world, check your changes, let it save, then quit.
6. Go back online. If Xbox asks which save to keep, choose the one on this PC.

If the edit is gone after going online, the cloud copy won: put your backup back and repeat the steps.
