Search engine and robots.txt for VB

[attroll]

I am using the robots.txt in my public_html directory and I would like to know what is recommended to disallow in the file. The reason I am asking is because I would like to get the most out of the google search engines that search my site and also maintain security at the some time.

I have been told to use the listing below in my robots.txt file but I really don't know if this is correct or if I have the right and wrong files in there.

Can I get some feedback on this or some recommendations, please?
