Careful - the comment was about mkisofs, although it was in the kernel
source. It definitely says file*systems* >2GB are legal, otherwise it
says mkisofs can't handle single *files* >2GB - that doesn't
necessarily mean they're illegal. The comment may also be old and no
longer true for current versions of standards.

You're mixing up file with filesystem here?

Yes, together with a raft of other iso9660 issues :(

Perhaps mkisofs is now able to handle files >2GB, the lack of a
suitable error when creating the filesystem does suggest so. However,
for Linux that's a moot point as Linux doesn't handle >2GB, but mkisofs
isn't only used on Linux. Thanks Gary for the warning about that.

It should be possible to retrieve the file with isoinfo -x, which
doesn't use any filesystem code.
