Then it's probably a 'sparse file', which means parts of the file
contain only zeroes and these are not stored on disk.
For example bittorrent prior to Version 3.3 created sparse files (and
huge file fragmentation).  You can try it yourself with dd:
dd if=/dev/zero of=bigfile seek=16M count=1
This creates a 8.1GB file which only takes 16K on disk. :-)
