Heya Mat,

Actually, I got this working;
inp: open/binary/direct ftp://ftp.site.com/big-file.bmp
out: open/binary/new/direct %big-file.bmp
buf-size: 200000
buffer: make binary! buf-size + 2
total: 0
while [not zero? size: read-io inp buffer buf-size][
write-io out buffer size
clear buffer
total: total + size
print ["transferred:" total]
]
close inp
close out
This works. The notable difference being the clear buffer, which was
actually just a guess from me since I don't really know what it does
other than resetting a pointer.
