Ahh.. mixing both manual update (copying files into a 
mirrror directory) and automatic one (updating using 
HTTrack the website) is quite complex, as HTTrack will 
either erase the files you put in the directorie(s), 
or will try to retransfer them.

The best way is NOT to filter the new files in 
HTTrack, and run an update process. HTTrack will 'see' 
that new files have been added in the directory by 
someone else, and will try to handle them. This often 
works, but sometimes not - expecially when the server 
doesn't understand the 'continue' request for a file 
which is.. completed!
