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.

How can I open a UTOC file?

You need a suitable software like Unreal Engine to open a UTOC file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your UTOC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a UTOC file directly in the browser:.

Programs that open and convert UTOC files:

Unreal Engine
See the previous paragraphs to learn more about the main application. UTOC files are often referred to as Unreal Engine data files because this type of file is primarily created or used by this software.
Unreal Engine
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.

UTOC file extension format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. If there are problems opening a file, you must first determine the file format used. Our evaluation of the UTOC files is as follows:

The UTOC file extension is quite common and predominantly uses a uniform format. The two most common formats are as follows:

99% of all UTOC files start with the bytes -==--==--==--==-, which are crucial for this file format. If you open these files in a text editor, you will see only illegible characters. The file size is in the range of 560 bytes to 1 MB. It is a modern file type. Several words can almost always be found in the files, e.g. -==--==--==--==-. The file name global.utoc is characteristic of these files. Files like these are sometimes connected to windows, pakchunk, client, game, noeditor, sparkingzero, console and shooter.

All other UTOC files (1%) have no consistent format. These files sometimes refer to factory, suit, optional, server, woman, icons or more. If you want to find out which format your UTOC file belongs to, just click on the button "Choose your .utoc file to analyze".

How to solve problems with UTOC files

Associate the UTOC file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest UTOC file format. Search, therefore, e.g. on the manufacturer website after an available Unreal Engine update.
To make sure that your UTOC file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
