I need to change 300 files with extention .htm to .php on my HD. (I'm not talking about internal links), just the actual file name. Is there a way that I can do it in one click or do I have to do it one by one?

Are you on a *nix system?

If you own a Windows PC goto www.softbytelabs.com and download NameWiz, it's an amazing little program! (30 days free trial too)

*nix:

rename 's/htm$/[url=http://www.php.net/]PHP[/url]/' *.htm

Windows:

rename *.htm *.[url=http://www.php.net/]PHP[/url]
