SGA File – What is .sga file and how to open it?

Definition of SGA Files

An SGA file is a Relic Entertainment Game Archive, specifically an archive file format utilized by video games developed by Relic Entertainment, a Canadian video game developer. These files function as containers and can house a variety of resources, such as textures, models, sounds, animations, and game data, which are essential for running the game. SGA files contribute to the efficient storage and management of these resources, ensuring their accessibility during gameplay.

Usage and Compatibility

SGA files are primarily used in Relic Entertainment’s video games, including popular titles like the Warhammer 40,000 series and Dawn of War franchise. They are typically located within the game’s installation directory, and various tools and utilities can extract and view their contents. However, it’s important to note that SGA files are proprietary and specific to Relic Entertainment games, meaning they may not be compatible with software or platforms outside of the intended game environment.

Opening SGA Files Using RelicSuite Toolkit:

RelicSuite Toolkit is an essential tool developed by Relic Entertainment for manipulating and extracting files from various game archives, including SGA files. It provides a comprehensive suite of features, allowing users to open, view, and edit SGA archives. To open an SGA file using RelicSuite Toolkit, simply navigate to the “File” menu and select “Open.” Browse to the location of the SGA file and click “Open.” RelicSuite Toolkit will load the contents of the archive, displaying all the files and folders it contains. You can then extract specific files or folders by selecting them and clicking the “Extract” button.

Alternative Methods for Opening SGA Files:

In addition to RelicSuite Toolkit, there are several third-party tools and libraries that can be used to open and extract SGA files. One such tool is sgax, an open-source Python library specifically designed for handling SGA archives. To use sgax, install it via pip (e.g., “pip install sgax”) and run the following command:


python -m sgax extract path/to/sga_file path/to/output_directory


This command will extract all files and folders from the SGA archive to the specified output directory. Another alternative is SGA Extractor, a standalone tool with a graphical user interface. Simply drag and drop the SGA file onto the tool’s window to open it, then select the files or folders you want to extract and click the “Extract” button.

SGA File Format

The .SGA file extension stands for Relic Entertainment Game Archive. This file format is primarily associated with video games developed by Relic Entertainment, a Canadian video game developer. SGA files are used to store various game data, including models, textures, audio files, and other assets required for the game to function properly. They are essentially archive files that compress the game’s data into a single container, making it easier to manage and distribute.

SGA File Structure

SGA files are composed of a header section followed by a data section. The header contains information about the file, such as the version number, the number of entries in the file, and the offset of each entry. The data section contains the actual game data, which is stored in a compressed format. The compression algorithm used in SGA files is proprietary and may vary depending on the version of the file. SGA files can be opened and extracted using various tools, including the SGA Extractor developed by Relic Entertainment.
