Figuring out where a file downloads from

Is there any way to figure out where a file is downloading from when if you push a button on the website it automatically forces you to download it?

I think the button is running a script so when I look at the source code all I see is a command that says

I would really like to know where it is pulling from because I have several files I want to pull and I don't want to have to go to every single page and hit this button to get them from each page individually.

Any ideas?

If you're using firefox, go to the download window, right-click on the file you've just downloaded, and select copy download link.

paste the link into notepad
