# removingLastComponent()

Creates a new path with everything up to but not including
`lastComponent`.

```
func removingLastComponent() -> FilePath
```

## Discussion

If the path only contains a root, returns `self`.
If the path has no root and only includes a single component,
returns an empty FilePath.

Examples:

- Unix:
  - `/usr/bin/ls => /usr/bin`
  - `/foo        => /`
  - `/           => /`
  - `foo         => ""`
- Windows:
  - `C:\foo\bar.exe                 => C:\foo`
  - `C:\                            => C:\`
  - `\\server\share\folder\file.txt => \\server\share\folder`
  - `\\server\share\                => \\server\share\`
