2.5.14 Determining the nFib


The nFib value specifies the version number of the file format that is used. The proper nFib value for the current document is determined in the following way:

  1. Read the FIB from offset zero in the WordDocument Stream.

  2. Check the value of FIB.cswNew.

  • If the value is 0, nFib is specified by FibBase.nFib.

  • Otherwise, the value is not 0 and nFib is specified by FibRgCswNew.nFibNew.
