can i know how you download the file ?? cos bittorrent normally using a installer to download one !! it just like kazaa ... although you can download straight from the webpage but the file is not viewable.. however, i'm here to advice you not to choose bittorrent ... because the installer will actually over boost your harddisk speed limit to accept the file !! after certain period then you will found bad sector in ur hard disk one ... but i did heard ppl say there are some bittorrent has no this problem !! so i'm not so sure about this also !! :D
