Config Manager is a Minecraft utility mod that lets modpack developers ship default configuration files without overwriting player preferences for Minecraft Fabric, NeoForge, and Quilt.
Config Manager solves one of the most common modpack headaches: how do you provide recommended settings without trampling the user's own choices? That matters because players expect a pack to be polished, but they also expect their controls, graphics tweaks, and mod settings to stay intact. With more than 1.3 million downloads, this mod has clearly found an audience among pack authors who need a cleaner way to manage configuration files.
Key Features of Config Manager Mod
- Pack defaults live in a dedicated folder — Put your modpack's baseline files in
/config/modpack_defaultsand keep them separated from the rest of the pack. That structure makes it easier to understand what the pack owns and what the player owns, which is important when you maintain or update a large mod list. - Missing files are filled in automatically — On startup, Config Manager copies files from that folder into the Minecraft directory only when they do not already exist. In practice, that means a fresh install gets the intended defaults, while an existing player profile keeps its own settings untouched.
- User preferences stay protected — The mod is built around the idea that defaults should not overwrite personal configuration unless you explicitly choose to do that. For players, that avoids the frustration of redoing keybinds, graphics options, or mod settings after every update.
- Nested config paths are supported — The examples show both flat files and deeper paths, such as
.minecraft/config/modpack_defaults/config/myMod.jsonbeing copied to.minecraft/config/myMod.json. That is useful if the modpack needs to ship files into the same folder structure the game and other mods already expect. - Update mode refreshes pack-owned settings — From the mod list on NeoForge or Mod Menu on Fabric, you can open the Config Manager interface and choose an update action. This lets you apply newer pack defaults where needed without forcing a full reset of every file on the player's machine.
- Reset mode restores a clean baseline — The reset action wipes the config directory and replaces it with the modpack's shipped files. That is a practical fix when a profile is corrupted, heavily drifted from the intended setup, or simply needs a fresh start.
- Built for modern modloader workflows — The mod supports Fabric, NeoForge, and Quilt in the versions listed here. That makes it a flexible choice for modpack authors who want one configuration workflow across several loader ecosystems instead of maintaining separate processes.
How to Install Config Manager Mod
- Choose the loader page that matches your setup: Fabric, NeoForge, or Quilt.
- Download the build that matches your Minecraft version from the download section below.
- Place the mod jar into your
modsfolder and make sure the required loader is installed first. - Launch the game once so the mod can initialize and, if you are a pack creator, add your defaults to
/config/modpack_defaults. - Open the in-game mod list or Mod Menu entry and use the update or reset tools only when you actually want to refresh shipped configs.

Frequently Asked Questions
Is Config Manager good for modpacks?
Yes — it is designed for modpack developers who want to ship default config files in a controlled way. The main benefit is that it seeds a player's installation with pack values without immediately overriding personal preferences.
Does Config Manager overwrite existing config files on startup?
No — it only copies files when they do not already exist. That behavior is the core of the mod's value, because it lets you set up defaults while leaving established user settings alone.
Can I reset configs with Config Manager?
Yes — the GUI includes a reset option that wipes the config directory and replaces it with the files shipped by the modpack. That is useful when a profile is broken, messy, or drifting too far from the intended pack setup.
Does Config Manager work on Fabric, NeoForge, and Quilt?
Yes — the provided data lists support for Fabric, NeoForge, and Quilt. It is also described as working on Minecraft 1.20.1 and newer, with download entries shown for 1.20 through 1.21.11 and the 26.1 line.
Where do I put default config files?
Put them in /config/modpack_defaults. Config Manager then copies those files into the Minecraft directory structure on startup when the destination files are missing.
What kinds of files can it manage?
It can manage regular config files and other shipped defaults that belong in the Minecraft directory tree. The examples include options.txt and mod JSON configs, which shows that it works with both game settings and mod-specific files.
Should regular players install this?
Usually yes if they are joining a modpack that depends on shipped defaults, and no if they are only looking for a gameplay feature. The mod is most valuable when the pack itself needs a clean, consistent configuration workflow.
