     *
     * ```ts
        const u = URI.parse('file://server/c$/folder/file.txt')
        u.authority === 'server'
        u.path === '/shares/c$/file.txt'
        u.fsPath === '\\server\c$\folder\file.txt'
    ```
     *
     * Using `URI#path` to read a file (using fs-apis) would not be enough because parts of the path,
     * namely the server name, would be missing. Therefore `URI#fsPath` exists - it's sugar to ease working
     * with URIs that represent files on disk (`file` scheme).

     * `URI.parse('file://' + path)` because the path might contain characters that are
     * interpreted (# and ?). See the following sample:
