File access vs Directory access control Apache2

I have got the directory access to work where it requires a user and
password to access the files in that directory, but I have yet to figure out
how to do this at the file level and not directory. Anyone here have any
ideas? Here is the directory commands that work:

<Directory "F:\inetpub\wwwroot\secure">
AuthType Basic
AuthName "Email request for access to: me@domain.mine, or enter user name
and password provided to you"
AuthUserFile "d:/program files/apache group/apache2/bin/passwords"
Require user user
</Directory>

Thanks Dan
