TRANS.TBL
Extracted from the Wikipedia article ISO 9660.
Other extensions
Native support for using TRANS.TBL still exists in many ISO 9660 implementations, particularly those related to Unix. However, it has long since been superseded by other extensions, and modern utilities that create ISO 9660 images either cannot create TRANS.TBL files at all, or no longer create them unless explicitly requested by the user. Since a TRANS.TBL file has no special identification other than its name, it can also be created separately and included in the directory before filesystem creation.
