Hello John, An ISO file contains capital letters A-Z, digits 0-9, underscores, periods, or semicolons. It has a max depth of 8 levels in the directory. In general it should be limited to 8 characters with a three character extension. Level 2 or Level 3 may contain up to 31 characters but when run on a DOS cachine the file names get truncated to 8.

I wanted to clarify the use of dots (.) and semicolons. The format of an ISO 9660 File Identifier is: NAME.EXTENSION;VERSION The NAME and EXTENSION can contain Upper Case letters A-Z, digits 0-9, and underscore (_) characters. The VERSION can only contain digits, representing a number from 1 to 32767. Under Interchange Level 2 and 3 (supported by Mac, Unix, etc.), the total length of the NAME plus the EXTENSION cannot exceed 30 characters. Under Interchane Level 1 (supported by DOS) limits you to 8 characters and the NAME and 3 character in the EXTENSION. The rules for Directory Identifiers are slightly different. Directory Identifiers only have a NAME. No dot, no EXTENSION, no semicolon, no VERSION. Under Level 2 and 3, the NAME can have up to 31 characters. Under Level 1, the NAME can have only 8 characters.
