After running for two days, WinHTTrack reported that the download of that large
website was completed. I found however that there were only about 3500 files
in the download directory, and that there were 2 zip files in the hts-cache
directory (old.zip and new.zip) that contained more than 10000 files. Strange?
I'm unpacking the zip files now - the files in the download directory are not
complete at all, I hope now that the files that I'm expecting are contained in
the cache zip files.
