There is nothing worse than surviving for 20 hours in the pitch-black corridors of the Dargroth dungeon in Spark in the Dark, only to lose your entire progression to a corrupted save file, an unexpected game crash, or a Steam Cloud sync error overriding your latest run.
Because this hardcore dungeon crawler relies heavily on punishing mechanics and autosaves, manually backing up your playthrough is essential to preserving your sanity. Whether you want to transfer your save data to a new PC, recover a lost character, or modify the configuration file to uncap your frame rate during massive enemy ambushes, you first need to know exactly where the Unity engine stores its data on your hard drive.
Below are the exact, verified file paths for Spark in the Dark across Steam, Epic Games, Xbox Game Pass, and Steam Deck, along with the safest way to automate your save backups to cheat the permadeath system.

🔥 Expert Note: The Cloud Sync Danger
“We have all been there. You are deep into Spark in the Dark, your torch is flickering out, you are bleeding from a trap, and your PC crashes right as you enter a new dungeon level. When you relaunch, Steam Cloud accidentally overwrites your local save with an older version, or worse, deletes the character entirely. It is a dungeon crawler’s worst nightmare. I specifically wrote this guide because Unity engine save management can be tricky. Even if you don’t plan on using memory trainers, please back up your SaveGames folder manually right now. Do not let hours of careful looting vanish in an instant.”

Windows PC Save File Location (Steam & Epic Games)
(Quick Answer: Presse Victoire + R, type %LOCALAPPDATA%Low, and look for the Stellar Fish folder.)
For players who purchased the game on Steam or other PC storefronts, the save files are generated by the Unity Engine and are generally located in the hidden Windows AppData LocalLow directory.

The exact file path is:
How to navigate there quickly:
Press the Touche Windows + R to open the Run dialog box.
Type %localamppdatalow% and press Enter.
Scroll down and open the folder named Stellar Fish, then open the Spark in the Dark dossier.
Open the Économise folder. Your character run files are located here.
Remarque : If you cannot see the AppData folder manually, open File Explorer, click the View tab at the top, and check the box for Hidden items.
Xbox Game Pass / Microsoft Store Save Location
If Spark in the Dark is played via PC Game Pass, Microsoft encrypts the save data and stores it in a completely different, highly protected system folder.
The Windows Store file path is:
Inside the wgs (Windows Game Saves) folder, you will see folders with long alphanumeric strings. These are your encrypted save files. Backing these up manually is incredibly difficult because the file names are randomized. (See the XMODhub Save Manager section below for an easier automated solution).
Where to Find the Spark in the Dark Config File
If you are trying to manually tweak graphics settings that are missing from the in-game menu (such as disabling heavy volumetric fog, forcing V-Sync off, or altering the FOV to see more of the dark corridors), you need to edit the configuration file.
The Config path is:
How to Edit: Right-click the Settings.json file and select Open with Notepad. Avertissement : Always make a copy of the file before changing values. Deleting or breaking a line of code can cause the Unity engine to crash on startup.
Steam Deck / Linux Save Location
Playing Spark in the Dark on the go? The Steam Deck uses Proton to emulate the Windows file structure. Your save files are buried inside the compatdata dossier.
The Steam Deck file path is:
Conseil : You will need to know the specific Steam App ID for Spark in the Dark, which is 1360060. You can always verify this number by looking at the game’s URL on the Steam Store website.
Troubleshooting: Steam Cloud Sync Errors
If your save file keeps disappearing or reverting to an older version where you lost all your newly crafted gear, Steam Cloud might be conflicting with your local files.
Cliquer avec le bouton droit de la souris Spark in the Dark in your Steam Library and select Propriétés.
Under the General tab, toggle Steam Cloud to OFF.
Play the game, force a manual save at a camp, and then exit.
You can safely turn Steam Cloud back on, and it should upload your newest local save to the servers.
The Smarter Way: 1-Click Auto-Backups with XMODhub

XMODhub automatically creates a secure backup of your save file every time you exit the game or press a custom hotkey.

Frequently Asked Questions (FAQ)
Q: Can I transfer my Spark in the Dark save file to another PC?
A : Yes. For Steam users, simply copy the entire contents of the Économise folder mentioned above onto a USB drive, and paste it into the exact same directory path on your new computer.
Q: What happens if I accidentally delete the config file?
A : Do not panic. If you delete Settings.json, the game engine will automatically generate a brand new, default config file the next time you launch Spark in the Dark. All your graphics settings will just revert to their defaults.
Q: Can I get banned for backing up my save to avoid permadeath?
A : No. Manually backing up your local save file (often called save-scumming) in a single-player environment will not result in a ban. Just ensure you do not use modified files if the game ever introduces official multiplayer leaderboards.
