I want to download a website that contains text-files 
without the .txt extension.

Winhttrack V3.20RC4B works fine and recognizes the text-
files. Unix-version 3.03 works fine too.
But Unix-Version 3.20RC4B doesn't recognize the text-files 
and stores them as html-files.
I used the same settings, even -c2!

I didn't try RC8 yet, but maybe you can check it anway.

Thank you!
