Thanks Tim,

One learns something every day. I had read about sparse files but
never used them, since I come from an IBM 32-bit OS/2 (HPFS)
background which I used for almost a full decade (1992-2002) and it
didn´t have sparse file support, not even in the os2 implementation of
JFS I believe -which arrived late, by around 1999.

When I used Linux and FreeBSD, I was no longer doing any low-level
programming, only bash and rexx, so I didn´t bother to research this.

So thanks for the heads up. I´ve found the following page which
details an interesting application of sparse files for virtual
machines http://administratosphere.wordpress.com/tag/sparse-files/
