Do you know a good software to download all PDF links in a web page??
Operating system is Windows 7.
You can use wget and run a command like this:
UPDATE: Since your update says you are running Windows 7: use wget for Windows from a
UPDATE 2: For a graphical solution - though it may be overkill since it gets other files too is DownThemAll
Copy and paste this, open a console enter
To use a download file, join the lines with "\n" and use the parameter as follows
Note that most other (gui) download programs too accept to be called with a space separated list of urls.
Hope this helps. This is how I generally do it. It is faster and more flexible than any extension with a graphical UI, I have to learn and remain familiar with.
If you want to stay in the browser, I've written a web extension for exactly this purpose - I'm working on adding the ability to save scholarly article PDFs with properly formatted titles but if you just want to download 'em all it's perfect for this.
It's called Tab Save and on the Chrome web store here. You don't even have to input the list of URLs if you just open them all in tabs (but for large numbers of files this might slow a computer down so I added the option to add your own).
