Extract text from Firmware and data files (EFD)
To convert EFD Data files to another format, you need WiTECH or other Data software.
To convert other file formats to the "Firmware & Configuration" file type, you need software like WiTECH or a similar tool.
The .efd extension is a classic example of a "filename collision," where multiple unrelated software ecosystems use the same three letters for entirely different purposes. The most common use (approx. 36%) is for Automotive ECU Firmware, specifically within the ecosystem of Fiat Chrysler Automobiles (now Stellantis). These binary files contain engine mapping, fuel injection timing, and sensor calibration data. They are strictly proprietary, encrypted, and designed to be read only by authorized diagnostic tools like WiTECH or specialized ECU tuners. Attempting to open these in a standard text editor results in unintelligible garbage, and modifying them without checksum correction can brick a vehicle's computer.
However, you may also encounter .efd files in other contexts. In the gaming world, titles like X-COM: Apocalypse and mobile games like Endless Frontier use this format for configuration and save data, often requiring hex editors to modify. In the events industry, ExpoCAD uses .efd to store floor plan data for trade shows. Users dealing with ExpoCAD files often face the frustration of needing expensive software just to view a booth layout. For these users, the practical solution is converting the proprietary .efd layout into a universal viewing format like PDF or a standard vector format like DXF or SVG for easy sharing and printing. For ECU files, conversion is generally limited to raw BIN or HEX dumps for analysis by engineering software.
Convert.Guru analyzes your EFD file, detects the exact format, and lets you read the text inside.
Users also converted PTS, LCP and VTP 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 EFD converter.
