I created batch files using HTTrack command line 
version, then use Scheduled Tasks prgram in Windows NT 
to fire them up in order to let them run on scheduled 
times, but it won't download the updated files from 
the source web site, then I added --cache=0, it seemed 
to be able to download not only the updated files but 
the whole web site, any ideas?  The syntax I used for 
the batch files is as follow:

"c:\httrack.exe" <http://www.[sourceweb].com> --
path="c:\Mirrors" --proxy=proxy:1008 --depth=2 --max-
rate=10000 --near --user-agent="HTTrack/3.0x" --
robots=0 --cache=0 --single-log -e -I0 -B +*.png
