Where Are Little Nightmares III Save Files Located?
Where Little Nightmares III keeps PC saves in AppData, how the Linux Proton path works, and the account lock gotcha.
Last updated
Little Nightmares III runs on Unreal Engine 4 and saves like it, in a Saved/SaveGames tree under LocalAppData. The folder name uses the Roman numeral III, which trips up searchers typing three capital Is. Config files sit in a WindowsNoEditor folder beside the saves.
Linux players go through Proton, so saves hide inside the Steam compatdata folder for app ID 1392860 and mirror the Windows layout within. Steam Cloud syncs between PCs on the same account. Saves refuse to work on any other account, so there is no point hand-editing someone else's files in.
Where Little Nightmares III stores this, by platform
%LOCALAPPDATA%\LittleNightmaresIII\Saved\SaveGames
Unreal style Saved tree: SaveGames holds progress, Config/WindowsNoEditor holds settings. AppData is hidden, so paste the path into Explorer. Back up the whole LittleNightmaresIII folder with the game closed. Cloud sync covers same-account moves.
~/.local/share/Steam/steamapps/compatdata/1392860/pfx
Proton prefix for app ID 1392860; inside pfx the layout mirrors a Windows drive, so continue to drive_c with the Windows path. Steam Deck uses the same compatdata root under the deck home folder. Account locking applies here exactly as on Windows.
Frequently asked questions
how do I back up Little Nightmares III saves
Copy the LittleNightmaresIII folder to external storage with the game closed. On Steam with cloud sync on, saves also follow your account to a new PC automatically. Keep a manual copy anyway before reinstalls, since cloud conflicts pick winners silently.
how do I open the save folder quickly
Paste %USERPROFILE%/AppData/Local/LittleNightmaresIII/Saved/SaveGames into the Explorer address bar. AppData is hidden by default, so the Run dialog or the address bar beats clicking through folders. Note the Roman numeral III in the folder name.
can I share saves with a friend
No. Saves are locked to the purchasing Steam account and do not transfer to a friend's account. Sharing the folder copies files the other account cannot use. Each player needs their own playthrough on their own account.
