Add data files to existing burn

I am trying to add more data files to a CD created using NeroAPI with the BurnOptions = NERO_BURN_OPTIONS.NERO_BURN_OPTION_USE_JOLIET and the following burn:

Call mobjDrive.BurnFileSystemContent _
(mobjFileSystem, _
NERO_BURN_FLAGS.NERO_BURN_FLAG_WRITE Or _
NERO_BURN_FLAGS.NERO_BURN_FLAG_VERIFY Or _
NERO_BURN_FLAGS.NERO_BURN_FLAG_CLOSE_SESSION, _
mintWriteSpeed, _
NERO_MEDIA_TYPE.NERO_MEDIA_CDRW Or
NERO_MEDIA_TYPE.NERO_MEDIA_CDR)

I have read in this forum about using the folder returned by OnDoneImport2 to accomplish this, but I am not creating an ISO burn (at least I don’t think so).

Could somebody steer me in the right direction?

Thanks :rolleyes:
