Introduction: The Data Conversion Dilemma In the world of automotive engineering, telematics, and data analysis, file formats are the silent gatekeepers of productivity. Two of the most common proprietary formats you will encounter are BLF (Binary Logging Format) , developed by Vector Informatik, and MF4 (Measurement Data Format 4) , the standard defined by ASAM (Association for Standardization of Automation and Measuring Systems).
