What is a .UTOC file?
UTOC is an Unreal Engine IoStore table of contents for cooked game data.
- Did you know
- UTOC indexes the packed assets of a shipped Unreal Engine game.
- UTOC is the Unreal Engine IoStore table of contents, listing each cooked asset’s id, offset and size so the engine can locate data inside the paired .ucas store.
- IoStore’s .utoc and .ucas pair was introduced to load shipped Unreal games faster than the older monolithic .pak archive.
- What Analyser reads
- Identify and read more game and emulator files: Unity asset bundles, Unreal cooked assets, CISO/CHD disc images, FMOD/Wwise sound banks, Spine skeletons and atlases, GameMaker/LDtk/TIC-80 projects, Minecraft Anvil regions, Warcraft III maps, Ren Py and RPG Maker data, extra console ROMs (Atari, PC Engine, Master System/Game Gear, WonderSwan, 3DS homebrew), xdelta/Basis patches and emulator saves and movies.
- Depth of analysis
- .UTOC is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .UTOC file
- Drag a .UTOC file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
