Anyway, using the Best-zip option in WinRAR, such a file compresses down to 948KB while DotNet Zip compresses the same file down to 8.24MB (almost 10x the size). Now, certainly 8.24MB is a lot smaller than 953MB (original file's size) but is there some reason that DotNet Zip does not compress such a file tighter than it does?<br>\r\n<br>\r\n<br>\r\n",
