How Does Mod Organizer 2 Work?

Mod Organizer 2 (MO2) is a free and open-source mod manager for Bethesda games, such as Skyrim, Fallout 3, Fallout: New Vegas, and Oblivion. MO2 is a powerful tool that allows users to install, manage, and organize mods without affecting the game files.

MO2 creates a virtual file system that isolates the game files from the mod files. Instead of modifying the game files directly, MO2 creates a separate folder structure that contains all the necessary files for the mods. This approach has several advantages over mod managers, such as BG3 Mod Manager and Vortex.

One of MO2’s main advantages is that it allows users to install multiple versions of the same mod without overwriting each other. This is achieved by creating a separate folder for each mod version and then loading the appropriate version based on the user’s selection.

Another advantage of MO2 is that it allows users to create custom profiles, which can be used to switch between different mods and game settings. This is useful for users who want to play different modded games or switch between heavily modded and vanilla games.

It also includes several features that make it easier to manage mods, such as a built-in conflict detector, which alerts users if two mods are incompatible. It also includes a plugin sorter, which ensures that the plugins are loaded in the correct order, preventing crashes and other issues.
