Extract text from SGA files
To convert your SGA file to another format, you need Corsix's Mod Studio or other Game software.
To convert other file formats to the "Game Data Archive" file type, you need software like Corsix's Mod Studio or a similar tool.
The .sga file extension indicates a Relic Game Archive, a proprietary container format developed by Relic Entertainment for high-performance strategy games like Company of Heroes, Warhammer 40,000: Dawn of War, and Age of Empires IV. Functioning similarly to a ZIP or RAR file, it packages thousands of loose game assets - including WAV audio, DDS textures, LUA scripts, and 3D models - into a single compressed block to optimize loading times.
Users typically encounter these files when attempting to create mods, extract game soundtracks, or view character models. A common frustration is that standard archivers like WinRAR or 7-Zip cannot open or extract .sga files due to their specialized binary header and hashing algorithms. Attempting to edit them in a text editor produces illegible gibberish. To access the contents, you must use game-specific utilities such as Corsix's Mod Studio or the official Archive Viewer included in the game's Steam Modding Tools. For Hades players, an .sga file serves a completely different purpose as an animation data file, which can sometimes be converted to readable JSON text for modding logic.
Convert.Guru analyzes your SGA file, detects the exact format, and lets you read the text inside.
Users also converted SMF, PNG, JPEG, JPG, IWA, SAZ and OPK files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SGA converter.
