Why is downloads not complete?
Loss of Internet connection: This is one of the most common causes for partial downloads. The loss of Internet connection will automatically cause a download to be incomplete. Certain browsers allow you to resume incomplete downloads however this must also be supported by the web server.
Why does my download stop before it is finished?
Sometimes, the downloads stop due to the connection with the server is temporarily interrupted when the bandwidth hits its limit. It's possible that you will not be able to resume the download files if you are using a browser to download such files. However, most of the time, employing a Download Manager can help.
