Hi,

I often notice that HTTrack downloads multiple copies of 
the same file from the server. This is probably because the 
same file can be accessed through different URI's.

I think this can be easily prevented by creating a hash 
(MD5) code of all downloaded files. If HTTrack downloads a 
file whose hash code matches a previous downloaded file it 
can just point the link to that other file. This will 
prevent multiple copies of the same file in the mirror 
directory.

Am i right?
