\fB\-file_size_limit\fR value [value [...]] --
Set the maximum permissible size for a single data file. The values get
summed up for the actual limit. If the only value is "off" then the file
size is not limited by xorriso. Default is a limit of 100 extents, 4g -2k each:

When mounting ISO 9660 filesystems, old operating systems can handle only files
up to 2g -1 --. Newer ones are good up to 4g -1 --.
You need quite a new Linux kernel to read correctly the final bytes
of a file >= 4g if its size is not aligned to 2048 KiB.

xorriso's own data read capabilities are not affected by eventual
operating system size limits. They apply to mounting only. Nevertheless,
the target filesystem of an -extract must be able to take the file size.

\fB\-split_size\fR number["k"|"m"]
Set the threshold for automatic splitting of regular files. Such splitting
maps a large disk file onto a ISO directory with several part files in it.
This is necessary if the size of the disk file exceeds MAX = 400 GiB - 800 KiB.
Older operating systems can handle files only if they are smaller than 2 GiB
or 4 GiB. But osirrox is not affected by eventual operating system size limits.
This is necessary if the size of the disk file exceeds -file_size_limit.
Older operating systems can handle files in mounted ISO 9660 filesystems
