Description

Header Config Manager is a Minecraft mod that allows modpack developers to ship configuration files in a simple and user-friendly way.
It supports both NeoForge and Fabric, starting from Minecraft 1.20.1 and newer.

Features

Ship modpack defaults without overriding user preferences

Place your modpack’s default configuration files in /config/modpack_defaults.
At startup, all files from that directory are copied into the Minecraft directory only if they do not already exist.

Examples:

.minecraft/config/modpack_defaults/options.txt → copied to .minecraft/options.txt
.minecraft/config/modpack_defaults/config/myMod.json → copied to .minecraft/config/myMod.json

This ensures that user settings are preserved across modpack updates.

Update or reset to the modpack’s defaults

From the mod list (NeoForge) or Mod Menu (Fabric), you can open the Config Manager GUI and choose between two actions:

Update – Copies (overwriting) the modpack’s config files on top of the user’s.
- All settings changed by the pack are updated.
- Untouched settings remain as configured by the user.
Reset – Wipes the entire config directory and replaces it with the files shipped by the modpack.
- Useful to fix broken or corrupted installations.

AllTheLeaks (Memory Leak Fix)

This mod fixes memory leaks of some mods, Neoforge and Minecraft until they implement their fixes.
