It bears two sessions. The PVD in block 16 points to the root directory
of the second session in block 2097234 = byte 0x100029000.
{{{
TOC layout : Idx , sbsector , Size , Volume Id
ISO session : 1 , 32 , 2097175s , ISOIMAGE
ISO session : 2 , 2097216 , 24s , ISOIMAGE
}}}
(There is a PVD in block 48 which points to the root directory of the
first
session. With Linux-specific mount option {{{sbsector=32}}} it is possible
to mount this first session.)
The data file content is stored at these places:
{{{
Report layout: xt , Startlba , Blocks , Filesize , ISO image path
File data lba: 0 , 55 , 1048576 , 2147483648 , '/file1'
File data lba: 0 , 1048631 , 1048576 , 2147483648 , '/file2'
File data lba: 0 , 2097239 , 1 , 18 , '/this_is_session_2'
}}}
