It depends on whether you have built your GnuPG with libcurl or not.   
Libcurl is a URL-fetching library that GnuPG can use to, well, fetch  
URLs.  If you are using libcurl then yes, you can use 'file' URLs.  If  
your GnuPG was not built with libcurl, the you can only use the 'http'  
method.

The easiest way to tell if you have libcurl support is to try doing:

   gpg --fetch-keys file://C:\smartkey.asc

If it works, then you're all set.  If it doesn't work, then you might  
try building your GnuPG with libcurl support.
