Where did you get "004568" from? Is it in the URL somewhere? Can you show a
complete URL?
Normally you can do this by setting a custom site structure in the build
options dialog
<http://www.httrack.com/html/step9_opt5.html>

The options are documented in the User Guide.

The default behavior is something like %h/%p/%n%q.%t.

In your example:

%h - www.website.com
%p - Ts
%n - name
%q - 57c5
%t - html
