File type: Game file
The ut4mod file extension identifies a MOD installation package for Unreal Tournament 2004. It packages additional game content for installation by the game's Unreal Module installer.
A ut4mod file is an Unreal Engine content-distribution archive that includes the files to install and information about their installation locations.

UT4MOD is the Unreal Module package format used by the Windows version of Unreal Tournament 2004. It is the successor to the umod and ut2mod filename extensions used by earlier Unreal games, but the underlying package format is the same.
An Unreal Module archive is an uncompressed collection of files together with installation metadata. The metadata specifies where the files belong in the game and can include required changes to Unreal Engine INI configuration files. A package may contain Unreal Tournament animations (ukx), audio files (uax), static meshes (usx), cache files (ucl), application packages (u), and textures (utx).
After Unreal Tournament 2004 is installed, Windows normally associates the ut4mod file extension with the game's installer. The format is a legacy package format for this older game. WOTgreal can work with Unreal game content, and UMOD Extractor can extract files from Unreal Module archives.
On Microsoft Windows, double-click a ut4mod file to open it with the Unreal Tournament 2004 installer if the file association is configured. To install it manually, copy the file to the game's System folder, open a command prompt there, and run setup.exe install filename.ut4mod.
UMOD Extractor can open and extract the contents of Unreal Module archives. If it filters by the UMOD extension, select All files in its file-selection window and choose the ut4mod file. WOTgreal is another Windows program for working with Unreal game content.
A ut4mod file is an installation package rather than an editable media or document format, so it cannot be meaningfully converted to another format. It can be extracted with UMOD Extractor, after which the individual Unreal Tournament 2004 files can be used separately.
