The file you've mentioned, "Francium-Client-Mod-Fabric-1.20.4.jar", appears to be a Java Archive (JAR) file, which is a type of file used by Java to package and distribute software, including mods for Minecraft. Let's break down the components of this filename to understand its implications and what it might indicate:
Francium-Client-Mod: This part of the filename suggests that the JAR file contains a mod for a Minecraft client, specifically named "Francium". The term "Client" usually refers to the part of the Minecraft software that end-users interact with, as opposed to a server, which hosts the game world.
Fabric: This indicates that the mod is designed to work with Fabric, a lightweight, modular, and highly extensible modding framework for Minecraft. Fabric allows modders to create mods that are highly compatible with a wide range of other mods and with the Minecraft game itself.
1.20.4: This version number corresponds to the Minecraft version that this mod is compatible with. Minecraft updates regularly, and mods are often version-specific because changes to Minecraft's internal code can break compatibility with existing mods. This particular mod is designed to work with Minecraft version 1.20.4.
While Francium Client can run alone, the Fabric API provides common code libraries that many mods (and certain Francium features) depend on. Download fabric-api-1.20.4.jar and keep it in the same mods folder.
