If You are Planning to do download with IDM… This is Suggestion for You..
Just go to IDM Setting and GO to File Types Remove ISO From the Lists.
Then Download via Google Chrome Or Mozilla Firefox and Copy the Link and Paste it into IDM. This is Because if You directly download via IDM It will create Non Resumable Download Link.
And If You follow what I am telling It will create Resumable Download Link.
