Subject: [PATCH 1/2] Add implementation for all path types

Avoid errors with Directory.GetFiles when specifying an absolute path. Old error:
```
Unhandled exception. System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.ArgumentException: Second path fragment must not be a drive or UNC name. (Parameter 'expression')
```
