Hi Vermillion,
>http protocol didn't like those filenames.
The filenames are OK, but you'd have to write %23 for the # symbol in the URL :-) Your file was actually properly accessible, but not via the link you provided.
(Knowing about %23 could be handy in case you find some interesting information posted by someone else, so that you can't change the filename.)
Regards,
