什么是 UTOC 文件？
A UTOC file stores the table of contents for an Unreal Engine IO Store container, a packaged, optimized storage system that bundles cooked game assets for faster loading and efficient runtime streaming. It contains metadata that the engine uses to locate and identify assets inside a paired .UCAS container, such as asset paths or IDs, byte offsets, compressed sizes, and compression or encryption flags. UTOC files are saved in a compact, binary format optimized for fast lookups at runtime.
更多信息
Unreal Engine creates UTOC files when developers cook and package a project using the IO Store system. The engine reads the UTOC first to find out where each asset is stored in the paired UCAS file. By using the UTOC and UCAS together, the engine can load game assets quickly during gameplay without needing to unpack many separate files.
如何打开 UTOC 文件
UTOC files are not meant to be opened. Instead, games built with the Unreal Engine load the files during gameplay. However, developers and modders may use tools to parse the UTOC to list packaged assets and to extract specific files from the UCAS container.
