Do you know a good software to download all PDF links in a web page??
Operating system is Windows 7.
Solution:
You can use wget and run a command like this:
wget --recursive --level=1 --no-directories --no-host-directories --accept pdf http://example.com
Or with the short options:
wget -r -l 1 -nd -nH -A pdf http://example.com
UPDATE: Since your update says you are running Windows 7: use wget for Windows from a cmd
prompt.
UPDATE 2: For a graphical solution – though it may be overkill since it gets other files too is DownThemAll
