I modified it to handle a filetype and URL as inputs, put it in my .bat "holding pen" and now can grab all of a given filetype from a URL easily.
Here's the contents of the filefetch.bat file (see the article for explanations of the switches):
wget -r -l1 -H -t1 -nd -N -np -w5 -A.%1 -erobots=off %2
It can be run like this:
filefetch mp3 http://sitename
Run this from the directory you want the mp3's downloaded to. The first argument is the file extension, so using mp3, gif, jpg, png, avi, etc. The second is the URL to start from. Make sure you pay attention to the -w5 setting, which spaces out your requests by 5 seconds. You only want the files, not to hammer the server into oblivion.
