Where Are Little Nightmares III Save Files Located?
Little Nightmares III keeps chapter progress and options in %LOCALAPPDATA%\LittleNightmaresIII\Saved\SaveGames, synced by two clouds.
Last updated
Little Nightmares III stores everything in %LOCALAPPDATA%\LittleNightmaresIII\Saved\SaveGames. Checkpoints and chapter progress live there as save files, and OptionSettings.sav beside them covers display, audio, and control choices. It is a small, flat folder, which makes backing it up trivial.
Two cloud services claim the directory. Steam Cloud covers the Steam version, Xbox Cloud covers the Microsoft Store and Game Pass builds, and a player running both can create exactly the conflict the FAQ below is about. Pick one store as home base and let the other sync only when the first is done.
Where Little Nightmares III stores this, by platform
%LOCALAPPDATA%\LittleNightmaresIII\Saved\SaveGames
Campaign checkpoints sit here with OptionSettings.sav for display and audio. Steam Cloud and Xbox Cloud both sync this folder, which is what causes the occasional version prompt.
~/.local/share/Steam/steamapps/compatdata/1392860/pfx/drive_c/users/steamuser/AppData/Local/LittleNightmaresIII/Saved/SaveGames
The Windows build through Proton on Linux and Steam Deck, inside the prefix for app ID 1392860. The same flat layout, and the co-op mode is playable on a Deck without fuss.
Frequently asked questions
Where is the Little Nightmares III save file?
%LOCALAPPDATA%\LittleNightmaresIII\Saved\SaveGames holds the campaign checkpoints, with OptionSettings.sav covering display and audio choices in the same folder.
Can I move a Little Nightmares III save between Steam and Game Pass?
The files are portable. Close the game, copy the save files into the same folder for the other version, and launch it once online so it syncs. Do not play the old copy again until the upload finishes, or the clouds will argue.
I only wanted to reset my settings. What do I delete?
OptionSettings.sav. Deleting it resets options on the next launch and leaves chapter progress untouched. The reverse is also true, which is handy when a settings change leaves the game unplayable.
