Not to be picky, but I think that it would take quite a bit longer to DL a 4.5GB file with your Internet connection.I have a 10 Mbit connection which gives me around 850 kb/s when I download from a fast server. A 4.5 GB download would take less than 1h 30min to download. Fully acceptable to me.
A 4.5GB file would be about 36 Giga bits.
At 850 kbps, that would take 42,353 seconds to DL.
That would be almost 12 hours by my calculations.
Maybe I am missing something.
