use nero and go to file options select joliet than you can use 64 characters long.
If the Microsoft defined “Joliet” (only for Windows NT and Windows 95!, -other operating systems (e.g. MAC) are not in the position to use it ) is activated, second parallel complete directory structure in UNICODE is created. It is important to know the receiver of the CD. In “Joliet”, file and directory names are allowed up to 64 characters long. There are no restrictions in directory depth, the typeface is extended. (The (first) ISO 9660 directory structure is created according to the ISO-9660-Standard. In the case that no Joliet rule is applicable, the ISO-9660-Standard takes precedence. For exact Joliet information see: Joliet CD-ROM Recording Specification/ISO 9660988, Extension for UNICODE, Version 1, May 22, 1995. Contact address: Microsoft Developer Relations Group.
A Video-CD must not be written with Joliet, because the special MPEG files have to be marked as mode 2, form 2 in order to be readable. This cannot be done in the Joliet directory structure, only in the ISO 9660 one. If a Joliet directory was written, Windows would not find this essential information.
