Some of you know by now I'm hosting my website and a personal file folder as web folders. Well I just decided to check on my bandwidth usage and this makes not the first time I've seen weird things on the monitor window.

There is no file in that folder called robots.txt, that's what's weird, and another one I see commonly is "favicon.ico", I see this pop up even when I see people who I know are browsing the site, but there is no favicon.ico file there. Does anybody know what these files are? They're not hidden either, I've looked.

There is no need to worry about these files beeing searched. robots.txt is used by the search engines when they indexing a site and favicon.ico is the little image at the left side of the URL in your address bar (the little penguin you see when visiting this site).
