I'm running HTTrack on a folder containing only data files 
(for instance, <http://www.unl.edu/images/>), and though all 
the files are mirrored just fine, I also get a bunch of 
index files that are NOT in that directory. They're 
strangely named, too: index5272.html, indexb3a7.html, and 
so forth.

How do I get rid of them?! I've tried every command line 
option I can think of, including -I0 and -C0, but nothing 
seems to help.
