This is quite similar to the question I asked a bit earlier...
So: is it possible to tell httrack to try to explore each folder root, so as
to find unlinked files?I mean: for each .../folder/file.ext found, try to
fetch /folder/ (or maybe folder/index.htm or folder/?M=D)
(of course, I don't intend to list protected directories, I want to explore
directories for which the server gives a default index page with folder
content)

PS: add +*/ is not a solution, it implies that */ is linked somewhere...
