apache 2.2 - Apache2: How do I restrict access to a directory, but allow access to one file within it?

I've inherited a poorly designed web app, which has a certain file that needs to be publicly accessible, but that file is inside a directory which should not.

In other words, I need a way to block all files and sub-directories within a directory, but over-ride it for a single file.

I'm trying this:

# No one needs to access this directly

   Order Deny,allow
   Deny from all

   # But this file is OK:
   

      Allow from all
   

But it's not working- it just blocks everything including the file I want to allow. Any suggestions?

Answer

There is an answer on StackOverflow that should answer this question, I think there is a missing Order in the nested Files directive?
