Maximum file size depends on the filesystem.  I run XFS (SGI's filesystem) on
Linux, and my max file size is 2^64 bytes :)  The problem is that the standard C
library uses signed 32 bit integers to index the file offset, so the practical
limit for 32 bit processors is 2GB.  Some operating systems offer support for
larger files. All these problems will go away in a year or two when 64 bit procs
are standard :)

My guess is that your friend runs NTFS and you run FAT32.
