PurePath represents a filesystem path and offers operations which
don't imply any actual filesystem I/O. Depending on your system,
instantiating a PurePath will return either a PurePosixPath or a
PureWindowsPath object. You can also instantiate either of these classes
directly, regardless of your system.

Path represents a filesystem path but unlike PurePath, also offers
methods to do system calls on path objects. Depending on your system,
instantiating a Path will return either a PosixPath or a WindowsPath
object. You can also instantiate a PosixPath or WindowsPath directly,
but cannot instantiate a WindowsPath on a POSIX system or vice versa.
