Extract text from Data archives (OAF)
To convert OAF Archives to another format, you need Techland Orion Engine or other Game software.
To convert other file formats to the "Game Data Archive" file type, you need software like Techland Orion Engine or a similar tool.
The .OAF file extension is primarily a proprietary game data archive file associated with the Techland Orion Engine, or alternatively, an Obsidian Archive File used by Obsidian Entertainment. These files package 3D models, textures, audio, and scripts required by the game engine into a single compressed container. In the heavy construction sector, the .OAF extension is also used as a 3D Machine Control file by Topcon Positioning Systems to feed grading and excavation blueprints directly into heavy machinery.
These files are heavily siloed. Game archives often use custom compression algorithms that prevent standard tools like 7-Zip or WinRAR from extracting the assets. Topcon .OAF files are similarly restricted to expensive, specialized software suites. This creates a major bottleneck for modders who want to modify game assets, or construction engineers needing to share topographical data with partners who do not have a costly Topcon subscription. Standard online converters fail because they lack the specific decryption keys or proprietary unpacking libraries required.
If you are trying to convert an .OAF game archive, your best targets are standard archive formats like ZIP or TAR to extract the internal PNG, WAV, or OBJ files. For Topcon files, you usually want to convert to universal CAD formats like DXF or DWG, though you risk losing proprietary machine calibration data.
Because .OAF is a closed, proprietary format, it is exceptionally difficult to open or convert without the original software. Often, only the engine or specific modding tools can properly read or export the data. Our system will analyze the headers, inspect the internal structure, and extract readable text or embedded media. If our analysis detects a supported underlying compression format, viewing or conversion may still be possible.
Convert.Guru analyzes your OAF file, detects the exact format, and lets you read the text inside.
Users also converted ODT, ODD, REL and YPT 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 OAF converter.
