Unix/Linux has something calle 'sparse' files used by some types of
databases where you can seek far into a file and write without
using/allocating any space up to that point. The file as stored may
not be large but most tools to copy it will act as though the empty
parts were filled with nulls. Rsync might handle them these days but
may still take the time to send the stream of nulls. But in any case
they are rarely used on Windows.
