I have more questions

What i have to do on import if I want to use file_system_container instead of write_cd structure. what is the optimal use of the cd in multisession.
how to check NBF_VERIFY with out error. for me if i specify nbf_verify it is ejecting and loading and then it is saying burn_cd failure even after i was able to open the cd and see the contents. for that what i have to do.

If you want to utilize IFileSystemDescContainer interface you will have to use NERO_WRITE_FREESTYLE_CD structure instead of NERO_WRITE_CD. Nevertheless you will have to import the previous session and to merge it into the IFileSystemDescContainer file system structure also specifying ‘nwcdpCDStamp’ parameter of NERO_WRITE_FREESTYLE_CD.
