I have pressed a CD-R on my PC machine with lots of files that need to be transferred to a MAC. However when I look at the files on the CD on the Macintosh the long names have all been truncated with the '~' sign.

How can I stop this from happening.

Don't use file names longer than 31 characters. That is the limit for the MacOS at present. Future versions of the MacOS will accomadate longer file names.

For the attention of 'the Hub'

the file names are less than 31 chars. They are being truncated after 8.

thanks

The ISO 9660 format does not support log file names.  The directory is kept in XXXXXXXX.YYY format (DOS 8.3) format.  Microsoft implemented the Joliet extension to ISO9660 to accomodate long filenames.  Try burning the CD with the Joliet format and reading it on the Mac.

The CD-ROM was pressed with the Joliet format on.

The Mac isn't able to read the joliet fortmat in the right way. You have to burn a MAC-formated CD or use the 8.3 name convention.

There is no solution for you if you are unable to accept the limitations of various naming conventions. You must apply a work around or live with the limitation.

As I said you have to burn your CD in a MAC-format.

Is there not a version of PC Exchange that will register the correct format of the ISO 9660 with longer filenames.
