The Australian bush of Big Walk is not a place you want to traverse twice simply because of a technical error. House House has crafted a massive open world filled with environmental puzzles, enigmatic structures, and a heavy emphasis on exploration. Because the game relies so heavily on intuitive discovery and physical navigation, progression is deeply tied to the physical state of your shared world. When you spend three hours manually carrying walkie-talkies, whiteboards, and flares across a canyon with 11 other friends, the last thing you want is for that progress to be wiped out by a corrupted save file or an accidental overwrite.

With the game supporting up to 12 players in drop-in, drop-out multiplayer, managing your save files safely is absolutely crucial. Different groups of friends mean different progression states, and PC players have a distinct advantage in being able to manually manipulate their local save data to juggle multiple friend groups. Based on community-reported Windows guides, this article details exactly where to find your PC save files, how to back them up, and how to safely duplicate slots so you never lose your hard-earned puzzle progress.

Why Backing Up Your Save Data is Essential

In a typical linear game, losing an hour of progress is annoying but manageable. In Big Walk, progression is entirely spatial and knowledge-based, heavily echoing the design philosophy of games like The Witness. You are physically moving items—megaphones, laser pointers, cowbells—from one side of the island to another to establish supply chains and communication outposts.

If the host’s save file is corrupted, or if a player accidentally loads the wrong session and moves crucial items around while others are offline, the entire ecosystem you built can be ruined. Furthermore, because of how how to host and join mechanics work, the player hosting the lobby retains the world state. If you are the designated host for a massive 12-player weekend expedition, you carry the responsibility of protecting that world state. Regular manual backups act as an insurance policy against crashes, bugs, or the chaotic griefing of a friend who thought it would be funny to throw all your walkie-talkies off a cliff.

Locating the Big Walk Save File on Windows PC

For players on Windows, House House utilizes the standard Unity engine file directory structure for storing local user data. While the game relies on Steam Cloud for standard syncing, your local machine always retains a hard copy of the world state.

According to community technical discussions, you can navigate to the save directory by following these specific steps:

  1. Press the Windows Key + R to open the Run dialog box.
  2. Type %USERPROFILE%\AppData\LocalLow and hit Enter. This will open the hidden AppData folder.
  3. Scroll through the list of developer folders until you find the folder named House House.
  4. Inside, open the Big Walk folder.
  5. Here, you will reportedly find a folder named Saves or a series of files with .sav or .json extensions that represent your world slots and character settings.

Keep in mind that the AppData folder is hidden by default in Windows. If you are navigating manually through your C: drive and cannot see it, you must click on the “View” tab in File Explorer and check the box for “Hidden items” to reveal it.

Step-by-Step Backup Instructions

Once you have located the Big Walk folder inside LocalLow\House House, creating a backup is incredibly simple and highly recommended before initiating any major massive 12-player expeditions.

To ensure the safety of your data:

  • Make sure the game is completely closed. Do not attempt to copy files while the game is running, as this can lead to incomplete data writing and immediate corruption.
  • Right-click the entire Saves folder (or the specific slot files) and select “Copy.”
  • Create a new folder on your Desktop or in your Documents directory. Name it something highly descriptive, such as Big_Walk_Backup_12Player_Saturday.
  • Paste the copied files into this new folder.

If your primary save ever becomes corrupted, or if your group makes a terrible mistake and loses all your megaphones in a ravine, you simply close the game, delete the corrupted files from the LocalLow directory, and paste your backed-up files back into their original location.

How to Duplicate Save File Slots for Different Groups

One of the most common issues players face is wanting to play the game with different sets of friends. You might have a dedicated two-player world with your best friend, and a chaotic 12-player world with your extended Discord server. While the game provides in-game slots, power users on PC often prefer manual save file duplication to bypass any UI limitations.

Community-reported methods suggest that you can duplicate a world state by copying the specific slot file (e.g., slot_1.sav) and renaming it to an unused slot number (e.g., slot_3.sav). This allows you to effectively branch timelines. You can keep one version of the world pristine for your serious puzzle-solving group, while letting another group run wild in the exact same world state without consequences. Be heavily cautious when renaming files, and always ensure you have a master backup stored elsewhere before manipulating the text names.

Managing Steam Cloud and Cross-Progression

When manually swapping save files, you must be hyper-aware of Steam Cloud sync conflicts. If Steam detects a discrepancy between your local files and the cloud files, it will prompt you to choose which version to keep. Always read this prompt carefully. If you are restoring a backup, you want to upload your local files to the cloud, overwriting the cloud’s potentially corrupted state.

For players utilizing multiple platforms, it is important to review our existing details on crossplay and cross-progression. Manually altering PC save files will sync to the cloud and affect your progression on other platforms, provided the cross-progression systems are fully active and synced. Managing your saves locally gives you the ultimate control over your group’s experience, ensuring that your time spent communicating, exploring, and struggling through the Australian bush is never wasted.
