Hell Let Loose stores its config files at %LOCALAPPDATA%\HLL\Saved\Config\WindowsNoEditor on Windows. That folder holds the settings rather than a save: keybinds, sensitivity, video options, the layout you arranged. Checkpoint64 already knows it, backs it up automatically and keeps every version, so a config that got reset is one click from restored.
Good to know: Very useful for reseting after crashes
Where Hell Let Loose settings are stored
- Windows —
%LOCALAPPDATA%\HLL\Saved\Config\WindowsNoEditor
or%LOCALAPPDATA%\HLL\Saved\Config\WindowsNoEditor
Where two locations are listed, which one is in use depends on the install (Checkpoint64 checks them in order and uses the first that exists).
How to open the config folder
- Windows — press Win+R, paste
%LOCALAPPDATA%\HLL\Saved\Config\WindowsNoEditor, and press Enter.
Backing up Hell Let Loose settings automatically
- Install Checkpoint64 (free) and pick Hell Let Loose — the config path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click after a patch resets your settings, a file verification restores the defaults, or you move to a new PC.
