Internet Download Manager (or often shortly called IDM) is a shareware download manager and accelerator tool for managing internet browser downloads, it is only available for the Microsoft Windows operating system.
DM allows users to automatically download certain file types, divides downloads into multiple streams for faster downloading and lists recent downloads for easy access to files, it also searches for mirrors in order to increase download speeds. Its algorithm includes dynamic segmentation throughout the downloading process. IDM has two version types, one is free which is a limit of 30-day trial (some versions are 15 day-trial), when this trial period expires the application will stop functioning and downloading until buying a license information, and one is commercial for continual use. IDM works with Internet Explorer, Opera, Netscape Navigator, Apple Safari, Flock, Google Chrome, Mozilla, and Mozilla Firefox.
