This is a bit dicey. If you give any file matching a pattern direct access it's possible for someone to abuse this to hack you. If you have no choice you can add the following to the "Custom .htaccess rules at the
top of the file" (mind you, don't use the one for the
bottom of the file, it won't work).
RewriteRule ^deleteme\.(.*)\.php$ - [L]
This tells Apache if the URL matches deleteme.*.php do not process any more rules, just run the file. Remember that the RewriteRule is a Regular Expression, hence the need to escape the dots with a backslash and add the ^ and $ (start of string and end of string matchers). The dash following the RegEx means "No action" and the [L] after that means "this is the last rule for this match, don't try to process any other rules".
I hope that helps!
