i support writing any values to the file but here is a list of the ones normally used.
Comments CompanyName FileDescription FileVersion InternalName LegalCopyright LegalTrademarks OriginalFilename PrivateBuild ProductName ProductVersion SpecialBuild
in addition i use CodePage and Language
you can only write to files that already have a stringfileinfo block and you are limited to the same or less total length so as not to corrupt the file.
