Retrieves attached file path based on attachment ID.
By default the path will go through the {@see 'get_attached_file'} filter, but passingtrue
to the $unfiltered
argument will return the file path unfiltered.
The function works by retrieving the _wp_attached_file
post meta value.
This is a convenience function to prevent looking up the meta name and provide
a mechanism for sending the attached filename through a filter.Related Functions: update_attached_file, get_attached_media, get_the_title, get_attachment_link, get_attachment_icon
