I've used HTTrack off and on for many years and it's always worked well,
however, when trying to download this site I noticed that any file that had a
filename of a single character was ignored.
Here's the website:
<http://resources.hwb.wales.gov.uk/VTC/2009-10/fph/ffrindiau-wyddor/index.html>

For example it will download CH.swf but not C.swf.

I can't believe this is a bug so am I missing something here?
