Hi all!I've already tried some of your tecniques to download all the pdfs files
from ukulelehunt.com and all its subpages.I've used in filters this option:
-* +mime:text/html +*.pdf

I've set the maximum depth to 20,the external one to 2.The browser identity is
Mozilla 4.0/MSIE 6.0.
In the folder there's no pdf.
This is the log:
