1) Always post the ACTUAL command line used (or log file line two) so we know
what the site is, what ALL your settings are, etc.
2) Always post the URLs you're not getting and from what URL.
3) Always post anything USEFUL from the log file.
4) If you want everything use the near flag (get non-html files related) not
filters.
5) I always run with No External Pages so I know where the mirror ends. I
always run with broswer ID=msie6 as some sites don't like a HTT one. I always
run with Attempt to detect all links.

If your broswer can see the directory, so can HTT

You did NOT try to resume, you tried to continue or update but its files are
not longer there, so it redownloads them.

Pause after xxx.
Or have it download to where ever you moved the files to.

Always post what you did #1 (there are no mind readers here)
Why do you need a filter(s) if you want everything?Do you really expect an
answer when you provide ZERO information on what you are trying to do?

It does this already. Update is very fast (about 2-3 files per second
depending on the round trip time to the server) and independent on the size of
the files.

There is already a pause and resume, can cancel/continue.

tmp files are temporary internal processing binary data. NOT you files. They
are gone once the file is downloaded. Stop canceling the download.

Not an HTT question.
Not if there are many people using HTT at the same time on a site. But I tend
to aggree. I think Xavier should have limited the connections/second to 1-2
since it is the requests that are the big drain.
