IJolietDiscMaster Interface

IID_IJolietDiscMaster

{E3BC42CE-4E5C-11D3-9144-00104BA11C5E}

The IJolietDiscMaster interface enables the staging of a CD data disc. It represents one of the formats supported by MSDiscMasterObj, and it allows the creation of a single Track-at-Once data disc. The data is written to the disc with the Joliet and ISO-9660 file systems.

A temporary folder is constructed and added to the image. This can be repeated multiple times with the directory and file structures overlapping. The overlapping file structures appear seamlessly when read back. When the overwrite option is used, overlapping paths cause the last file added to show up in the directory, while the earlier files with conflicting names are still present on the disc but now not readable by normal means.
