Thanks for your answer but I don't understand it, what is a
query string, and why should there be more files in the
mirror than in the original?

This is perfectly normal, nothing to do with my problem
though, which seems to be related to the spider encountering
several times the _same url_.

To be clearer, the url which gave me the problem is this
directory index url:
<http://fcpe.lattescollege.free.fr/IMG/>
If you run httrack (latest beta) on it, you find 9 spurious
index****.html files in the mirrors of IMG and of its subdirs.
