Thanks Xavier for all your patience answering my 
questions.  I really appreciate it.  I guess I asked too 
much for a free product.  It's a great software and farely 
easy to setup and use.

I need some advise for a current project. I try to mirror a 
big website with a lot of big speach files (around 5MB 
each, mp3).  From the website, the size is estimated at 
least 50G.  The website is structured in a hierachical way 
that top web pages display categories of speaches and the 
bottom pages are for each individual speach with multiple 
pages containing links to mp3 files on a ftp server.  With 
my past two day's experience, it looks like I have to set 
up a keep alive connection and let Httrack to download 
without stopping.  This may takes a couple of weeks to 
finish the project.  Stop the job and continue later did 
not seem to work for me in this case.

Anyway, any advise will be appreciated.

Thank,
Jesse
