What is a CGI file?

CGI stands for Common Gateway Interface. Files that contain the .cgi file extension are are script files that are written in the C or Perl programming languages. These files are used to create web pages and they are usually stored within the cgi-bin folder of a website directory. The files define how web server software delegates the generation of certain web pages including executable files and stand-alone applications. These are often referred to as CGI scripts.
