A DXB file comprises a file header followed by zero or more data records. Each data record begins with a single byte identifying the record type, followed by one or more data items. The DXB format should not be confused with the binary encoded version of the Drawing Interchange File Format (DXF) - DXB is an entirely separate format, being much simpler and more compact.
