Dear Gurus,
this is an edit of another posting that I recycled ;o)
Ok, my first question from the old posting is answered by something I found on the web.
and I can ask my second question now much more clearly, because now I know that the physical filesize and the size on disk are NOT equal because of something called clustering.
Ok, I nearly figured out how this works, but I don't know if I am right, so I ask you:
I need to dertermine the physical filesize and the space it occupies on disk.
the first one is easy, but how to get the size on disk ? As I understood, one needs to do the following:
int sizeondisk;
int m = filesize % clustersize;
if (m > 0)
{
sizeondisk = filesize - m;
sizeondisk += clustersize;
}
else
{
sizeondisk = filesize;
}
is this right ? if not, please tell me why.
Another question is how to determine clustersize. I did't find a way to get this value.
Ok, thanks in advance
Juergen
