Hide Folders If you have a folder you don't want everyone else in the world to see for some reason or another. Maybe it contains personal data? Then you can effectively "rope off" that area of your site from bots by adding the folder name. As an example say we have a folder called personal, and we don't want the bots to index it. We would then add /personal/ in one of the four boxes and it will block that area off when you create your fie. [ok back to robots.txt tool]
