What is a UTOC file?

UTOC files mostly belong to Unreal Engine. Unreal Engine TOC (UTOC) Files: This file is used by Unreal Engine to maintain an index of game assets. It works as a table of contents (TOC) and indicates where the actual asset data is stored. The engine uses it to efficiently locate and load assets such as .uasset files.

Asset Index: Contains entries that point to asset data.

Internal Use: Designed to be used only by Unreal Engine, not for manual editing.

Engine Integration: Operates with other asset files to keep the project organized.

For more precise technical details, refer to the official Unreal Engine documentation.
FilExt.com tip: It is best to manage these files using Unreal Editor to avoid issues.

A *.UTOC file is an Unreal Engine Table Of Contents file used by Unreal Engine. It stores information about the contents of a *.UASSET file, which is an Unreal Engine asset file. The *.UTOC file acts as an index, allowing the engine to quickly locate and load specific data within the associated *.UASSET file. This index contains information such as the names, types, and locations of the various objects and properties stored within the asset. By using a separate table of contents, Unreal Engine can optimize asset loading and improve overall performance. This file format is classified as Game Development.
