You can also rename it via telnet or your ftp program, and you should be familiar enough with one of those so as not to need explaining.
Using regular expressions you can have your rules matching a set of URLs at a time, and mass-redirect them to their actual pages. L - Last Rule. We have encased the regular expression part of the URL in parentheses, because we want to store whatever value was found here for later use.
The flags which I find to be most useful are: In short, the nearest htaccess file to the current directory is treated as the htaccess file.
