Where Are LEGO Batman: Legacy of the Dark Knight Save Files Located?
LEGO Batman: Legacy of the Dark Knight splits saves and settings across two Local AppData folders, one under Warner Bros. and one code-named Dinner.
Last updated
LEGO Batman: Legacy of the Dark Knight stores saves in %LOCALAPPDATA%\Warner Bros. Interactive Entertainment\LEGO Batman - Legacy of the Dark Knight\SaveGames. Settings live somewhere completely different: a Dinner folder in the same Local AppData tree, which is the game's internal project name and gives no clue about LEGO anything.
That split is the thing to know before a reinstall. Copying only the Warner Bros. folder preserves progress but loses your graphics and accessibility options, and copying only Dinner does the opposite. Steam Cloud is listed for app ID 2215200 and covers most moves, but manual backups should grab both halves.
Where LEGO Batman: Legacy of the Dark Knight stores this, by platform
%LOCALAPPDATA%\Warner Bros. Interactive Entertainment\LEGO Batman - Legacy of the Dark Knight\SaveGames
Story progress and level completion. Note the spaced dash in the folder name. Copy with the game closed; the folder appears after the first save.
%LOCALAPPDATA%\Dinner\Saved\Config\Windows
Graphics, input, and accessibility settings under the game's internal code name. Edit with the game closed, or the client rewrites the file on exit.
~/.local/share/Steam/steamapps/compatdata/2215200/pfx/drive_c/users/steamuser/AppData/Local
Steam Deck and Linux run the Windows build through Proton, so both folders above reappear inside the prefix for app ID 2215200.
Frequently asked questions
Where are LEGO Batman: Legacy of the Dark Knight saves stored?
In %LOCALAPPDATA%\Warner Bros. Interactive Entertainment\LEGO Batman - Legacy of the Dark Knight\SaveGames. Progress sits there as save files; back up the whole SaveGames folder with the game closed.
Why can't I find the LEGO Batman config file?
Because it hides under the project code name. Settings live in %LOCALAPPDATA%\Dinner\Saved\Config\Windows, not in a LEGO or Warner Bros. folder. Back it up along with SaveGames for a full move.
Does the game use Steam Cloud?
Yes, cloud sync is listed for app ID 2215200. That helps across machines but can also overwrite a manual restore, so pause sync while swapping save files and keep a spare until progress loads.
