Internet Download Manager is my secret shareware weapon when I want to download a video, image or file from a webpage in super quick time. Even if they are password protected, IDM lets you download all types of file and it is very fast. Provided you can see the page then you can download it.
Now at this stage I must warn you about downloading and stealing other people’s work. That isn’t on.
But if you want something from your own site but can’t access the file without a lot of hassle or if the file is available to the public and you want to bypass a complex download procedure …… then IDM is the answer .. and there was a free trial when I last looked.
