If you are going to make an ISO 9660 Level 1-compliant disc, take ISO 9660's filename limitations into consideration from the start when creating your files and applications. Use
this option to record discs with filenames which comply strictly with ISO 9660 Level 1 restrictions.
Any MS-DOS 8+3 filenames (unrestricted character set)
Windows 95/98/Me/2000/NT allows you to use file and folder names up to 255 characters long, which may include spaces. To maintain DOS compatibility, a DOS-standard (8+3)
filename is associated with each file; these names are created automatically by Windows and can be viewed in Properties for each file. To create these DOS-standard names, long
filenames are truncated and the tilde (~) character is added; a number may also be added to distinguish between files which would otherwise have identical names when truncated.
For example, the filename "Letters to Send.DOC" might become "LETTER~1.DOC."
Joliet
Joliet is an extension of the ISO 9660 standard, developed by Microsoft for Windows 95, to allow CDs to be recorded using long filenames (it also allows for using the Unicode
international character set). For files recorded to CD, Joliet allows you to use filenames up to 64 characters in length, including spaces.
Versions of Windows NT up to 3.51 build 1057 do NOT read the long filenames on Joliet discs. Windows NT 4.0 does support Joliet. If you select this option, filenames up to 64
characters long will be allowed. If a filename is longer than 64 characters, a message will appear allowing you to edit the filename.
Long File Names (30 characters max)
In Windows 95/98/Me/2000/NT long filenames are used, but converted to upper case. Filenames longer than 30 characters are truncated and the tilde (~) is added; a number might
also be added to distinguish between files which would otherwise have identical names when truncated.
Romeo
Romeo allows you to write to disc filenames up to 128 characters long, including spaces. This is not part of the Joliet standard, and the Unicode character set is not supported. If
read under DOS or Windows 3.1, file and directory names will appear truncated to 8+3. (However, if two or more filenames become identical when truncated, you will probably be
able to see only the first.) Romeo long filenames can be read on Windows 95 and Windows NT 3.51 systems.
When you select this option, your disc can include filenames up to 128 characters long. File and directory names are automatically converted to uppercase for maximum
compatibility with Windows NT 3.51 and DOS.
File Version Numbers
In strict interpretations of the ISO 9660 standard, all directory entries of files must contain the file name followed by a semicolon and the file version number, "1." Most operating
systems automatically remove these two characters from the filename when accessing a file or displaying a directory.
Some UNIX systems require a setting to make the version numbers "disappear."
Windows System Problems When Creating CDs
If you are experiencing problems with your Windows Operating System when creating CDs, try one or more of the following:
Close any open applications when creating a CD.
l
Turn off any screen saver, power management or suspend mode that might be enabled on your computer while a CD is being created. These can be reenabled once the CD
l
creation process has finished.
If you have anti-virus software installed, disable any active virus scanning during the creation of a CD or when copying a large amount of files to a disc. Make sure that you
l
reenable the active anti-virus software and scan the disc that you created before using or distributing it.
