Thank you for the reply!
My problem is not to get too many files. HTtrack stops after 7 seconds.
I start with
:http://fr.altavista.com/audio/results?q=gamelan&maf=mp3&mad=long
set the limits of max. mirror depth to 3
spider : no robots.txt rules
browser ID : default (Mozilla/ 4.5.....)

the journal file contains this :
"note: the hts-log.txt file, and hts-cache folder, may contain sensitive
information,
 such as username/password authentication for websites mirrored in this
project"

The reason is perhaps the family filter of Altavista????
No way?????What did you think?
Best regards
