/**
 *	Single use download variables
 *	Defines where the actual download location is
 *	Defines the path to the download file (download.php)
 *	Sets a fake files name to show to users (should not be the same name as the real file)
 *	Sets the admin password to generate a new download link
 *	Sets a date when the file will expire (examples: +1 year, +5 days, +13 hours)
 *
 *  Optional `remote_path` vs `protected_path` 
 *  With remote_path, you can link to an external file
 *
 * `file_size` is automatically calculated for local files, but manually set for remote files
