I would like to mirror local files independent of links in html. I may not have
linked all files. I would like to back up an entire directory structure with
Httrack and use the versatile file and directory filters. 

If I enter <file:///D:/local-directory> in my web browser, it shows me a list
files and subdirectories that I can browse.
If I enter <html://www.somesite.com/directory> in Httrack, it will mirror the
directory and subdirectores. If <html://www.somesite.com/directory> works in
Httrack, why can't I get <file:///D:/local-directory> to work?
TIA,
Phil A.
