- ## Method Details

  - ### getFile

    File getFile()
    Returns the file being visited.
    Returns:
      The file. Never returns null.

  - ### isDirectory

    boolean isDirectory()
    Returns true if this element is a directory, or false if this element is a regular file.
    Returns:
      true if this element is a directory.

  - ### getLastModified

    long getLastModified()
    Returns the last modified time of this file at the time of file traversal.
    Returns:
      The last modified time.

  - ### getSize

    long getSize()
    Returns the size of this file at the time of file traversal.
    Returns:
      The size, in bytes.

  - ### open

    InputStream open()
    Opens this file as an input stream. Generally, calling this method is more performant than calling `new FileInputStream(getFile())`.
    Returns:
      The input stream. Never returns null. The caller is responsible for closing this stream.

  - ### copyTo

    void copyTo(OutputStream output)
    Copies the content of this file to an output stream. Generally, calling this method is more performant than calling `new FileInputStream(getFile())`.
    Parameters:
      `output` - The output stream to write to. The caller is responsible for closing this stream.

  - ### copyTo

    boolean copyTo(File target)
    Copies this file to the given target file. Does not copy the file if the target is already a copy of this file.
    Parameters:
      `target` - the target file.
    Returns:
      true if this file was copied, false if it was up-to-date

  - ### getName

    String getName()
    Returns the base name of this file.
    Returns:
      The name. Never returns null.

  - ### getPath

    String getPath()
    Returns the path of this file, relative to the root of the containing file tree. Always uses '/' as the hierarchy separator, regardless of platform file separator. Same as calling `getRelativePath().getPathString()`.
    Returns:
      The path. Never returns null.

  - ### getRelativePath

    RelativePath getRelativePath()
    Returns the path of this file, relative to the root of the containing file tree.
    Returns:
      The path. Never returns null.

  - ### getPermissions

    FilePermissions getPermissions()
    Provides a read-only view of access permissions of this file. For details see `FilePermissions`.
