How to close CD/DVD?

Hello everybody.

when I’m burning without using NERO_BURN_FLAG_CLOSE_SESSION flag, cd or dvd become close and i cant burn into them nothing more. can i close cd or dvd without burning any file?

You probably could do it by burning an empty ISO track. What is the purpose anyway?

hi alexp

I want to burn folders into CD/DVD by multisession. That why I don’t want to close the media until I’ll try to burn and I’ll see that the media is full.

Do i have a possibility to figured out how much free space / trucks I’ll have on media after burning file/folder (i know file’s/folder’s size in bytes) ?

After burning one session, you can always ask for a disc info and see how much free space is left. If you want to know the size of a track prior to burning, you should use EstimateTrackSize().

hi alexp

what do you mean “size of a track prior to burning” ?

and how can i know for every filr i want to burn how many tracks it will take on cd/dvd?

sorry - not "how many tracks it will take " but “how many blocks it will take”

You can’t know how many blocks each file will take. You can only get the info about the total track size.

Thank you alexp :slight_smile:
