Uファイルとは?

A U file is a class package used by Unreal Tournament and other games built with the Unreal Engine. It contains compiled UnrealScript classes and settings that define gameplay behavior, objects, and logic. U files are used to add various features, such as weapons, power-ups, AI behavior, or even full game modes.

詳細情報

Developers and modders use tools provided by Epic Games, such as ucc.exe (Unreal Command Console), to compile their custom scripts into U files. Once compiled, users can distribute U files and drop them into the appropriate folder to modify or extend a game, similar to a plugin. For example, a modder might create a new weapon or character class in UnrealScript, compile it into a U file, and then load it into Unreal Tournament to use it during gameplay.

U files are typically stored in the game's System folder (for example, \​Unreal\​System\​).  When a game launches, the engine loads the relevant U files from the System directory to access the necessary gameplay code.

Uファイルの開き方

U files are not meant to be opened. Instead, the game packaged with the U file references it to load the information it stores.

However, gamers who enjoy modifying gameplay may extract and modify U files with tools, such as Dragon UnPACKer and Unreal Tournament Package Tool.
