These files are query-string URLs ; such as 
<http://www.example.com/index.php?id=1234>. HTTrack always 
handle collisions between URLs having different query 
string values, and generate as many files as there are 
different URLs.

If multiple URLs are generating the same content (such as 
<http://www.example.com/index.php?foo=<random-number>>;), you 
will end up with multiple copies of these files (there is 
no way to detect such cases before downloading the files 
remotely)
