Copy a file to a new location and adds a file record to the database.
This function should be used when manipulating files that have records stored in the database. This is a powerful function that in many ways performs like an advanced version of copy().
$source A file object.
$destination A string containing the destination that $source should be copied to. This can be a complete file path, a directory path or, if this value is omitted, Drupal's 'files' directory will be used.
$replace Replace behavior when the destination file already exists:
File object if the copy is successful, or FALSE in the event of an error.
file_save_upload() for details on temporary files.
see file_unmanaged_copy()
