It’s pretty odd that Microsoft should impose a limit on the number of files that can be downloaded simultaneously in Internet Explorer. In Internet Explorer version 8 and 9 the number of files that you can download at once is restricted to six, but it was worse in Internet Explorer 7 and earlier where Microsoft limited the number to mere two. The limit is sensitive to the connection speed. If the browser detects dial-up connections, both Internet Explorer 8 and 9 will revert back to the limits from earlier versions.
