No established vendor, purpose, platform, or format description is available for the .bi_ file. The extension alone is therefore insufficient to determine what the file contains.
The file's origin or the application that created it is needed to identify its format and intended use.
No specific program can be recommended for opening a .bi_ file. If the file came from a particular application, it should be opened with that application or identified using information from its source.
A .bi_ file cannot be converted reliably until its actual format and originating software are identified. No specific converter or export method is known for this unknown file extension.
