Please explain the NULL MAPPING options in the upsizing wisard

[jrumbaug]

When converting my data files to SQL with the upsizing wizard, there is an option called NULL MAPPING. The four options are:
1)general field overrides
2)general and memo fields override
3)all fields override
4)default settings

I am trying to understand the differences of these options. If I understand correctly, #1 allows nulls in most fields, #2 also allows nulls in memo fields, #3 alows nulls in ALL fields, but I am not sure what #4 does.

I believe it is more along these lines...

1) set fields of type General in my VFP database to allow nulls in SQL Server
2) set fields of type General and type Memo in my VFP database to allow nulls in SQL Server
3) set all fields in my database to allow nulls in SQL Server
4) respect the settings I already have for the fields in my database in SQL Server
