-- For example: WORD, 033.TIF, RESUME.DOC, LETTER.TXT, 12345678.900 The complete file name or path is limited to a total lenght of 65 characters. Operating systems like Novell allow longer file names and paths. These need to be shortened to 65 characters.

-- For example: WORD.;1, 033.TIF.;1, RESUME.DOC.;1, LETTER.TX.;1T, 12345678.900.;1 (DOS won't let you see the .;1). If the applications that you want to run on a Macintosh or Unix system look for a particular file or application , be sure and include the .;1 in that name.

How to make a fully ISO 9660 compliant CD-ROM disc for the PC and Macintosh.

• Volume name is limited to 11 alphanumeric and underscore characters in all CAPS.

For example: WORD.;1, 033.TIF.;1, RESUME.DOC.;1, LETTER.TX.;1T, 12345678.900.;1 (DOS won't let you see the .;1). If the applications that you want to run on a Macintosh or Unix system look for a particular file or application , be sure and include the .;1 in that name.

How to make a hybrid ISO 9660 CD-ROM disc for the PC and Macintosh

• Volume name is the same as above.
• Make two folders in the root directory. Label one MAC and the other PC.
• In the MAC folder/directory put all the standard Macintosh files. These folders and files will not be ISO 9660 compliant but will have the same naming conventions as do the standard Mac files. (31 characters max.)
• Macintosh icons don't lay out in a particular order and they will use a generic icon.
• In the PC folder/directory put all standard DOS files in the ISO 9660 format.
