IDM is the best platform for downloading a file and resuming from where it has stopped. suppose if we download a file from internet, our server goes down then we will have to star all over again. IDM solves all your problems for downloading from internet. It is a trail version available for only a month this the only drawback. I love most its resume capability. You need to spend roughly 1500 if you want to take it for lifetime and star downloading and resuming.
