Extract text from Game map files (D4C)
To convert D4C Maps to another format, you need Driver: San Francisco or other Game software.
To convert other file formats to the "Map Data File" file type, you need software like Driver: San Francisco or a similar tool.
The .d4c file extension is primarily a Game Map Data File utilized by the open-world driving game Driver: San Francisco, developed by Ubisoft. These files act as containers for streaming city geometry, texture coordinates, and collision meshes that render the game's massive recreation of San Francisco. Unlike standard 3D formats like OBJ or FBX, .d4c files are heavily compressed and optimized for the game's proprietary streaming engine, making them unreadable to standard 3D editors like Blender or Autodesk Maya without conversion. Users typically encounter these files when attempting to mod the game, extract city assets for fan projects, or analyze map layouts.
A secondary but significant use of the .d4c format is within the Google Earth ecosystem, where it serves as a data cache for streaming geospatial terrain and building photogrammetry. In both cases, the primary difficulty is proprietary lock-in: the data is intended for runtime execution, not editing. To use this content in other software, you must convert it. For 3D modeling, extracting to OBJ preserves geometry; for documentation, converting map overlays to PNG or PDF is ideal. For archiving game data without the heavy engine overhead, ZIP encapsulation is recommended.
Convert.Guru analyzes your D4C file, detects the exact format, and lets you read the text inside.

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 D4C converter.
