求翻译：Check the size of the movie file you have on your hard drive against the size of the movie listed on the movie page you downloaded from. If there is a difference in size, chances are that you have not downloaded the entire movie file. This is typically because your ISP terminated your connection momentarily, cutting off your download midway. You will need to download the movie file again.是什么意思？
