- * g_file_new_for_path() if you have a path.
- * g_file_new_for_uri() if you have a URI.
- * g_file_new_for_commandline_arg() for a command line argument.
- * g_file_parse_name() from a utf8 string gotten from g_file_get_parse_name().

- * One way to think of a #GFile is as an abstraction of a pathname. For normal
- * files the system pathname is what is stored internally, but as #GFile<!-- -->s
- * are extensible it could also be something else that corresponds to a pathname
