The mkisofs man page says iso/joliet/udf supports disk size up to 8TB
and maximum single file up to 8TB with udf only up to 200GB single file.


Personally I use the -UDF option to make an iso/udf hybrid as well as
iso-level 3 and get a message that "files larger than 2GB found. These
files will only be fully accessible if mounted with UDF"

Just tested a disk now - on a dvd-r medium. One file of 4.3G and another
of 29M

If I mount_udf I see one file of 4.3G and one 29M.

I find if I use mount_cd9660 I see two copies of the same file - showing
as 4G each and one 29M. I don't see any difference using any of the
options.

While that file size isn't a full 32 bit value it is close.

My guess would be that the iso driver is still using a 32bit filesize

df -h shows the cd9660 mounted size at 4.4G
