Note that while this method is very convenient, using it will imply
an assumed reference to the default
FileSystem and limit the
utility of the calling code. Hence it should not be used in library code
intended for flexible reuse. A more flexible alternative is to use an
Path instance as an anchor, such as:
Path dir = ... Path path = dir.resolve("file");
