=== Size Limitations ===
ISO 9660 filesystems can have up to 2 exp 32 blocks, i.e. 8 TiB.
Normally they will be restricted to the size of optical media.
(Currently up to 100 GiB with 4-layer BD-R.)
The maximum size of data files depends on the Level of Interchange
that is intended for the ISO filesystem. Levels 1 and 2 allow for
4 GiB - 1, because a single Directory Record can claim up to that
number of bytes. Level 3 allows to have multiple consequtive
Directory Records with the same name. They all are to be concatenated
to a single data file. This means that a single data file can nearly
fill up the full 8 TiB of image size.
