Problems resetting permissions

[A[L]C]

Hi,

 

I am using MiniServer (http://miniserver.sourceforge.net/) on my laptop and have installed OSCommerce on it. It all went fine, but it now says ive got to:

 

Reset the permissions on /catalog/includes/configure.php to 644 (if you are still getting the warning message at the top set configure.php to 444 which is read only - this happens on some servers that have been updated for security reasons).

Set the permissions on /catalog/images directory to 777

Reset the permissions on /admin/includes/configure.php to 644

Create the dir /admin/backups and set the permissions to 777

Set the permissions on /admin/images/graphs directory to 777

 

Now how do I do this as I havent FTP'd anything. Im running it on XP btw.
