On other people's file systems (Windows) the file size in the directory
structure is a 32-bit value, and so the display of file sizes are
limited to 4 Gbytes. But since the OS is 32 bits as well, the OS cannot
seek a file beyond the 4 GByte mark. On Netware traditional volumes it's
a 32-bit signed value, and files are limited 2 Gbytes.

I don't know how it works with ext2, ext3 or ext4 -- it seems to me to
be the same file system for both 32-bit and 64-bit operating systems.
Are there intrinsic limits on ext2, ext3 or ext4?
