BFA file format details:

The file format determines how the data is stored in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. If there are problems opening a file, you must first determine the file format used. Below you will find our evaluation of the BFA files:
