- - - - subPath(int, int)
        
        Return a relative subpath of the Path object, referenced by an INCLUSIVE start index and an EXCLUSIVE end index
    - - 「.」
        
        Reference to the current directory
      - 「..」
        
        Reference to the parent of the current directory
    - - getParent()
        
        If Path object is relative, this method will stop at the top-level element defined in the Path object.
      - getRoot()
        
        If Path object is relative, return null
    - - getNameCount()
        
        Retrieve the number of elements in the path
        
        If the Path object represents the root element itself, return 0
      - getName(int)
        
        Reference to each element in the Path
        
        zero-indexed
  - - - Copying Files with java.io and NIO.2
        
        copy(<InputStream>, <Path>)
        
        copy(<Path>,<OutputStream>)
  - - - All metadata about a file will be copied with it.
    - - If the target file exists, it will be replaced. If it is NOT provided, an exception will be thrown if the file already exists.
    - - Symbolic links when encountered will be traversed.
    - - The operation is performed in an atomic manner within the file system, ensuring that any process using the file sees only a complete record.
      - Method using it may throw an exception if the feature is unsupported by the file system.
    - - Symbolic links when encountered will NOT be traversed.
- - - - Windows-based absolute file
