Garry's Mod Config File Location (Windows)

Garry's Mod stores its config files at C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\cfg 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 earlier versions, so a config that got reset is one click from restored.

Where Garry's Mod settings are stored

  • Windows — C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\cfg

How to open the config folder

  • Windows — press Win+R, paste C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\cfg, and press Enter.

Backing up Garry's Mod settings automatically

  1. Install Checkpoint64 (free) and pick Garry's Mod — the config path above is already preset.
  2. Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
  3. 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.

Common questions

Where does Garry's Mod store config files on Windows?

Garry's Mod keeps its settings at C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\cfg. Checkpoint64 already knows this path and backs the folder up automatically.

Can I back up Garry's Mod settings automatically?

Yes — Checkpoint64 watches Garry's Mod's config folder and uploads a new version every time it changes, so you get automatic backups with version history. Free download for Windows and Linux.

How do I restore my Garry's Mod settings?

With Checkpoint64, open the config folder's version list and restore any earlier version in one click — it puts those exact files back, so every keybind and video setting comes back together. Without a backup there is nothing to go back to: the game rewrote the folder with its defaults.
