Greatings,

I am building an application that will be used to write data files to a CDRW. I can build the NeroFileSystemDescContainer and RootDirectoryContainer successfully. I can burn the CDRW successfully using BurnFileSystemContent successfully. But, I can't figure out how to add files after the burn. The CDInfo.FreeCapacityInBlocks comes back as zero and I have to use EraseDisk to be able to put anything else on the disk. If I run the Nero Express application there is a flag called "Allow files to be added later (multisession disc)" that does what I want, but I can't figure out how to do that from the SDK.

Thanks in advance for your sage advice.

My Nero API Version is 6.3.1.25

I have solved my problem. It seems that NERO_BURN_FLAG_CLOSE_SESSION means just the opposite. The following call works:

Call mobjDrive.BurnFileSystemContent _
(mobjFileSystem, _
NERO_BURN_FLAG_CLOSE_SESSION Or _
NERO_BURN_FLAG_VERIFY Or _
NERO_BURN_FLAG_WRITE Or _
NERO_BURN_FLAG_DETECT_NON_EMPTY_CDRW, _
mlngSpeed, _
NERO_MEDIA_CDRW)
