Presumably this is just a limit of the mkisofs program. ISO 9660 : 1988 (E) 9.1.4 says a 32 bit number is used to specify the Data Length in a Directory Record, but that is just the number of bytes in that particular File Section. ISO 9660 : 1988 (E) 9.3.e specifies no limit for the number of File Sections in an individual File. Directory Entries for all of the File Sections must be in the same Directory. ISO 9660 : 1988 (E) 6.8.1 says that a Directory shall consist of only one File Section. Given that limit of 4GB on the size of any File Section (and thus a Directory) assuming a Directory Record size of 64 bytes (to make the math easy), it seems to me a Directory could contain 62,500,000 of those records for successive File Sections. Multiply the 62 million Directory Records in a single Directory by the 4 billion bytes in any File Section and you have a limit considerably larger than 2 GB. You need a bigger disc than CDROM, and there may be operating systems that cannot handle such sizes, but I see no problem in the ISO 9660 format up to about 2**18 bytes in a file. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
