I am deliberately not making assumptions to how httrack works as I have only
very vague idea how crawling works - thus far it must be obvious from my
previous posts.

However, please kindly note "or not to save" in original question:

>> Is there a way of specifying during the update 
>> not to fetch, or not to save html files previously fetched? 

I would be really grateful if someone could confirm the _no_   as the answer
to : 

Is there functionality in httrack not to save the html files if they were
previously saved?
