You can change the initial page that is sent to client requests when a directory is accessed by placing the following line into your .htaccess file:
Replace "filename" with the actual file you wish displayed when someone visits the directory where your .htaccess file exists. By default, the webserver will display a file named "index.html". If that does not exist, then it displays "index.htm". If that does not exist, then it displays "index.shtml" Finally, if that does not exist either it displays "index.cgi". If there is not index.cgi file either it lists all of the files in the current directory.
