Thanks for your answer. Sorry - I dont want to post the actual site, because
the zip folder is hidden (not linked) and I dont want everyone has access to
it without the full path. Hopefully, you would help me anyway ...

Do you mean this with command line? Im using the GUI:

(winhttrack -F "Mozilla/4.5 (compatible; HTTrack 3.0x; Windows 98)" -%F "<!--
Mirrored from %s%s by HTTrack Website Copier/3.x [XR&CO'2010], %s -->" -%l
"de, en, *" <http://user:pass@www.test.com/zip> -O1 "d:\MySite\te" +*.wmv
+*/*File* )


The structure is the following:

www.test.com/zipfolder
      |-----/zipfolder/folder1
      |-----/zipfolder/folder2
      |-----/zipfolder/folder3
      |-----/zipfolder/folder4
      |-----/zipfolder/folder5
      |-----/zipfolder/folder6

In this folders are different files, but no html with links (zip, rar, aso)

So I would like HTTrack to download from "www.test.com/zip" AND all subfolders
only the zip files. Is that possible, or do I have to specify all the folders
by itself?
