Thank you for reply.

I have to disagree, however.

Why?
Because I have just set up thttpd on cygwin, filled it up
with 3-4 zip files and ran httrack to fetch them.

The result is exactly the same as with the online sites -
that is, file-size filtering does not work as expected.

httrack.exe <http://localhost> "-*[>1000].zip" -O "V:\htt_temp\checktypetest"
-A90000 -f -z -Z

Does not fetch any *.zip file, giving:

01:11:37 Debug: lower link authorized: localhost/files/
01:11:37 Debug: (wizard) explicit forbidden (-*[>1000].zip) link: link
localhost/files/ at localhost/
01:11:37 Debug: (wizard) cancelled foreign domain link: link localhost/files/
at localhost/

and removing "-*[>1000].zip" makes it fetch them, of course.

I have also tried "-*[> 1000].zip" (quoted, as you see it),
still the same result.

I'm really pulling out my hair here.
I think I will take an another look at the source code tomorrow.

What do you think?
