What is a RAT file?

File used by implementations of the PICS (Platform for Internet Content Selection) Web rating system, which is used to rate websites based on content; saved in a plain text format and specifies categories for rating explicit material such as language, sexual material, and violence.

More Information

RAT files are used for installing rating systems on computers, which block access to websites that meet the PICS rules criteria. Microsoft's Content Advisor component, which is integrated with Internet Explorer, can use RAT files to install a rating system that helps deny access to certain websites. To install a rating system, double-click the RAT file.

NOTE: The PICS system is not widely supported, but Internet Explorer's Content Advisor can still use PICS RAT files.
