Join joins any number of path elements into a single path,
separating them with an OS specific [Separator]. Empty elements
are ignored. The result is Cleaned. However, if the argument
list is empty or all its elements are empty, Join returns
an empty string.
On Windows, the result will only be a UNC path if the first
non-empty element is a UNC path.
