Free Disc Space

How can I tell how much free disk space is left? For example on a multisession disc. I'm using VB also so I may need to convert data types. I say in the disc_information structure, some items were 4 characters, do I have to convert that to a double or something?

Just call StarBurn_CdvdBurnerGrabber_GetTrackInformation and then
SizeLeftInBytes = Track_Info.m__LONG__FreeLBs * 2048

Bye.

What is the invisible track information? I saw references to it in the doc but couldn't find anything else about it.

Does it matter which track I look at to get the free size? If so, which one do I get.

"Invisible" stands for "current track would be used for burning". It has pre-defined number 0xFF (255 in dec). You should pass it always to know about free space on the disc. Using exact track numbers is not recommended.

If I try to calculate whether there is enough room on my disk to burn the files I want to burn, I add up the size of my files. Do I also need to add in the size of the TOC? Do I need to consider anything else?

Just add 15 megabytes to your virtual (or true) image size. It would be enough for TOC and file system structures overhead.
