Err, without a cache, this is going to be harder. Start the 
project and use "update" or "continue" ("continue" should 
also detect "old" files, but NOT corrupted ones)
You will loose all html files ; but "regular" binary file 
should be detected and the engine should send an update 
request remotely. Some server will fail, unfortunately, to 
provide necessary information so that httrack can avoid to 
download unnecessary data.
