This can be either INDEX FILE or WHOLE FILE. If we're defining a WHOLE FILE index, the fields in the index are defined in a subfile, but the index itself physically resides at a higher level. In our case, the fields in the index will come from the EMAIL multiple, but the index will reside at the top level of the file. This enables us to lookup entries in the ZZINDIVIDUAL file given an email address.

If we're not defining a whole-file index, the Root Type is INDEX FILE and File and Root File are equal. The index resides at the same file level as the fields in the index. This enables us to look up entries in the EMAIL multiple for a particular ZZINDIVIDUAL file entry.
