Configured Defaults
by Fuzs
With Configured Defaults installed, a modpack pack maker can ship config files that land in a player's folder only where none exist yet.
What it does
The mod reads a configureddefaults folder and places any file or folder that is absent from the game directory. Modpack creators use it to distribute default configuration files, which matters most when a new mod arrives in an update: players receive the intended settings rather than values the mod generates on its first launch. Files already present are left alone, so the copy only fills gaps.
The mod is not limited to configuration files. Any path inside the game directory can be supplied this way. The options.txt file gets separate treatment: instead of being replaced, missing entries are merged in from the default version, so new settings are added while a player's existing preferences are kept.
Either side can run the mod, and neither needs it, since it is optional on the client and on the server. It is published for Fabric, Forge and NeoForge. The 27 release versions cover 1.18 – 26.3, and the license is the Mozilla Public License 2.0, which makes the mod open source. Its source code and issue tracker are public. The project credits shedaniel and a separate foundation mod as its base.
Key features
Missing file copy
Files and folders absent from the game directory are placed from the configureddefaults folder, and existing files stay untouched.
Options merge
Missing entries in options.txt are merged from the default file, adding new settings without overwriting a player's current choices.
Update-friendly defaults
When a mod is added in a modpack update, its intended configuration reaches players before the mod first launches and writes its own defaults.

Use cases
Modpack updates
A pack maker adds a mod in a new release and ships the matching config files in the configureddefaults folder.
Server default setup
Server owners place default files for a fresh server directory so that new installs start with the intended setup.
Who it’s for: Modpack creators who distribute configuration files, and server owners who want a consistent starting setup for new installs.
