Unfortunately I cannot back it up. I only have 4.3gb of fat32 space
total. And it would be my guess that truncate() would need to use the
function that I'm guessing every other program is failing on because it
can only handle 2^31 bytes. I'd love to just see somebody who knows what
they're doing patch the libs to be able to handle, say, 2^63 byte files...
Is that even doable ? Or would an unsigned long int work ?
It's sad, out of this 2.6gb file, I'm only interested in probably less
than a megabyte of it :) -- dunno if those files are at the beginning or
the end.
