This size can only be represented in the UDF filesystem.
Make sure that your clients support and use it.
ISO9660, Joliet, RockRidge, HFS will display incorrect size.

The 4 GiB (or 2 GiB depending on implementation) file size limit

All numbers in ISO 9660 file systems except the single byte value used for the GMT offset are unsigned numbers. As the length of a file's extent on disk is stored in a 32 bit value³, it allows for a maximum length of 4 GiB. (Note: Some older operating systems may handle such values incorrectly, i.e. signed instead of unsigned, which would make it impossible to access files larger than 2 GiB in size.)

Based on this, it is often assumed that a file on an ISO 9660 formatted disc cannot be larger than 232-1 in size, as the file's size is stored in an unsigned 32 bit value, for which 232-1 is the maximum.

It is, however, possible to circumvent this limitation by using the multi-extent (fragmentation) feature of ISO 9660 Level 3. With this, files larger than 4 GiB can be split up into multiple extents (sequential series of sectors), each not exceeding the 4 GiB limit. For example, the free software mkisofs as well as Roxio Toast are able to create ISO 9660 filesystems that use multi-extent files to store files larger than 4 GiB on appropriate media such as recordable DVDs.

Empirical tests with a 4.2 GiB fragmented file on a DVD media have shown that Microsoft Windows XP supports this, while Mac OS X (as of 10.4.8) does not handle this case properly. In the case of Mac OS X, the driver appears not to support file fragmentation at all (i.e. it only supports ISO 9660 Level 2 but not Level 3). Linux supports multiple extents [4]; FreeBSD only shows and reads the last extent of a multi-extent file.
