Path to extensions...

I can't get PHP to find the path to my extensions. I have PHP installed at C:\PHP and have created a directory called 'extensions' and put all of the .dll's in there. I modified the line in php.ini to read "extension_dir = .\extensions" . Now PHP won't start and gives me error messages on the server stating that it can't find the php_fdf.dll. First of all I need to know the basics: Do I use a '/' or a '\' in the php.ini file? Where does it assume the root folder is? where the core PHP files are or where the php.ini file resides? This is frustrating.. I'm soooo close. :) Todd
