Isolinux and long filenames
can they be longer than with syslinux

 11:19 pm on Aug 16, 2002 (gmt 0)

I'm trying to create a bootable CD (3 unsuccessful tries till now), I think I got it now. I'm testing with syslinux first but I think it has a much tighter filename length limit.

Has anyone created one, I would like to know how long filenames I can use, the docs say that with ISO level 2 I should be able to get 31 chars, but I don't understand why syslinux has a different limit.

Isolinux version 1.75.

Thanks everybody.

What you need to look for when researching on CD and long names are the Joliet and/or RockRidge extensions. From the syslinux documentation, isolinux uses plain iso9660 filenames, that means no extension filenames.

<added> Maybe you got the impression that by using syslinux every file on the disk should be length limited. That is not right; only isolinux will read still the short names, you can use any length allowed by rockridge or joliet by passing -R -J to mkisofs.

Well I haven't yet burnt a successful CD, but I managed to get a running environment on my hard disk with syslinux.

It is slightly different but I am not sure if isolinux will support longer filenames than syslinux does.
