Do I need a download manager? When making the decision as to whether or not you need a download manager depends on a few things. If you download a large number of files or files that are large in size then a download manager may help you to organize them. A download manager can also help as you can schedule the downloads- this way the files will download even when you turn your computer off or you have exited from your browser. You will not need to monitor the downloads as the program will do it for you.
