If you’ve ever wanted to fix a corrupted game install, back up your settings before a big title update, or tweak small quality of life details for your single player hunts, you’ve probably come across mentions of monster hunter wilds base files. A lot of players avoid touching these files entirely because they’re worried they’ll break their game or get hit with an account ban, but they’re actually a really useful tool when you understand how they work. This guide breaks down everything you need to know to work with these files safely, no advanced tech skills required.
What Exactly Are Monster Hunter Wilds Base Files?
Put simply, these are the core, default files that Monster Hunter Wilds runs on when you first install the game. They store all the default settings that don’t change based on your personal play progress, from monster health values and item drop rates to the default UI layout and cutscene files. Base files control every core mechanic of the game, separate from your personal save files that store your hunter’s gear, hunt progress and collected monsters.
On PC, you can find these files in your Steam directory by default, under steamapps > common > Monster Hunter Wilds > base. Console players won’t be able to access these files directly, since they’re encrypted to prevent cheating on online platforms. You don’t need to mess with these files at all if you’re happy with the default game experience, but they’re good to be aware of if you want to customize your play or fix common errors.
It’s important to note the difference between base files and mod files. Most quality of life mods only add extra files on top of the base game, rather than overwriting the core base files, but some larger total conversion mods will require you to replace certain base files to work properly. That’s where most players run into trouble if they don’t take the right precautions first.
Common Safe Uses for Monster Hunter Wilds Base Files
There are a ton of legitimate, low-risk reasons to work with these files, as long as you stick to non-competitive single player mode only for any modified versions. The most common use is backing up the base files before installing any mods. If a mod ends up conflicting with a new game update or breaking your install, you can just replace the modified files with your backed up base files instead of having to redownload the entire 70+ GB game again.
Another common use is fixing corrupted file errors that pop up after Steam updates or unexpected game crashes. Sometimes a single base file will get corrupted during an update, leading to constant crashes on launch or loading screen freezes mid-hunt. Replacing that single corrupted file with a clean version from your backup fixes the issue in minutes, no full reinstall needed. A lot of players also edit small base file values to adjust things like FOV beyond the default in-game slider limit, or turn off unskippable intro cutscenes they’ve seen dozens of times.
Before you make any changes at all, there are three non-negotiable rules you need to follow to avoid issues:
If you’re looking for pre-tested safe base file tweaks for single player use, you can find curated, community-vetted options on Nexus Mods' Monster Hunter Wilds page. Every file uploaded there is scanned for malware and tested by thousands of players, so you don’t have to worry about accidentally bricking your install if you follow the posted instructions.
Risks of Modifying Base Files Without Proper Preparation
Even small mistakes when editing these files can lead to big headaches, so it’s important to know what you’re getting into before you start changing things. The biggest risk by far is an anti-cheat ban. Capcom’s anti-cheat system scans all core game files every time you connect to online servers, so even a tiny change like increasing your FOV by 10 degrees will get flagged as a modified client. I’ve seen dozens of players post on community forums complaining they got banned after forgetting to revert their base files to default before joining a friend’s online lobby, so it’s not a risk you want to take.
Another common issue is corrupted game installs. If you edit a config file incorrectly, or overwrite a base file with a version that’s not compatible with your current game update, you might find the game crashes every time you try to launch it, or gets stuck on loading screens when you try to start a hunt. In worst case scenarios, a bad base file edit can even corrupt the link between your game and your cloud save, leading to you losing hundreds of hours of hunt progress, rare gear and collected monster research.
You also run the risk of breaking mod compatibility if you edit base files without checking what changes your installed mods make. A lot of popular mods edit the same base files, so overwriting one without checking can lead to conflicts that cause random crashes mid-hunt or make certain mod features stop working entirely.
Step-by-Step Guide to Backing Up and Restoring Base Files
Backing up your base files only takes a couple of minutes, and it saves you hours of hassle down the line. First, make sure you close Monster Hunter Wilds completely, don’t just minimize it, otherwise some files will be locked and you won’t be able to copy them properly. Next, navigate to the base file folder in your Steam directory, right click the folder named “base” and select copy. Paste the folder to a separate drive on your computer, not in your Steam folder, so even if you have to uninstall Steam entirely you still have access to the backup.
Label the backup folder with the current game version number so you know which update it matches if you need to restore it later. Capcom releases title updates every few months that change multiple base files, so an old backup from a previous version won’t work properly if you try to use it after an update. To restore your base files, just delete the modified “base” folder in your Steam directory, paste your backup folder in its place, and verify the game files through Steam to make sure everything matches the current official version.
For console players, you can’t manually access or back up base files, but you can restore the default base files if you’re having issues by using your console’s built-in game file repair tool, or uninstalling and reinstalling the game entirely. If you’re playing on console, you won’t be able to make any custom edits to base files anyway, since they’re encrypted to prevent cheating on online servers.
At the end of the day, monster hunter wilds base files are a really useful tool for customizing your single player experience, fixing common game errors, and protecting your progress, as long as you follow the simple safety rules we covered. You don’t need to be a tech expert to work with them, and taking five minutes to back up your files before you install any mods will save you so much frustration later. If you’re ever unsure about a change you want to make, check community forums first to see if other players have tested it, and always err on the side of caution when it comes to modifying files you might need later.
