More About

Backward Compatibility Mode

When backward compatibility mode is enabled, any new CDF file created using version 3.0 or later of the CDF library will be readable by clients using version 2.7 of the library. Version 3.0 and later of the CDF library use a 64-bit file offset to allow for files larger than 2 GB. Versions of the CDF library before version 3.0 use a 32-bit file offset.

Tips

• This function corresponds to the CDFgetFileBackward routine in the CDF library C API.

• To use this function, you must be familiar with the CDF C interface. You can access the CDF documentation at the CDF website.
