Vector’s flagship simulation tools (CANoe, CANalyzer) natively love and ASC files. While they can import MF4, the playback engine performs best with BLF. Converting MF4 to BLF allows for:

An ASAM international standard. It is highly flexible, supporting both message-based (raw CAN frames) and signal-based (decoded physical values) data. It is the successor to the older MDF3 (.dat/.mdf) formats and features a complex block-based hierarchy for efficient large-scale data storage. BLF (Binary Logging Format): A proprietary format developed by Vector Informatik . It is the native format for Vector’s mf4 to blf
