Joliet is in fact an extension of ISO9660 and in many ways exactly the same. ISO9660 is recorded in a number of duplicate structures (with different byte order) You should also read the section Options \ File System settings as you are able to influence how ISO is interpreted based on these duplicate structures. IsoBuster shows this with following Icons : SUN MAC Sometimes this File System mentions for what system the CD was mastered. Of course IsoBuster has no problems with these CDs as well. This shouldn't be a problem as of Windows 95 OSR2 but these CDs might cause problems in other systems. Some mastering application sin against these limitations and allow to master ISO9660 with long file names and more directories deep. However you need it if you want to see the content of the CD in an old DOS mode or an older Mac or Sun system.
Because of these limitations it is almost always accompanied by one or more File Systems that don't have these limitations. It is however also the oldest and has some major disadvantages such as short file names (8.3) and a directory structure which can only be 8 levels deep. The most common File System on all CDs and DVDs is the ISO9660 File System.
You will recognize a File System as the icon connected to a Track or Partition icon in the left view. It also provides alternative ways in case one File-System is corrupt but the other one isn't ! It's is a very powerful feature of IsoBuster in it's quest to be able to recover 'all' data ! IsoBuster scans for all File Systems it supports and will show them all ! This allows for the user to select the File System he/she requires. In some cases however, File Systems DO differ and one File System may for instance contain a driver to be able to read the other File System. In most cases the different File Systems point to the same files and the reason for the different File Systems exists to support as many different Operating Systems as possible. There can be more than one file system per Session or Partition. To understand the TOC better, read the section about the CD/DVD Layout. The TOC describes the session and track layout of a CD or DVD it does not describe the files and folders. On optical media (CD, DVD, BD) a File System is often confused with a TOC but it is not. The File System describes where and how on the media the files and folders are located.
