/**
		 * The string representing the corresponding file system path of this Uri.
		 *
		 * Will handle UNC paths and normalize windows drive letters to lower-case. Also
		 * uses the platform specific path separator.
		 *
		 * * Will *not* validate the path for invalid characters and semantics.
		 * * Will *not* look at the scheme of this Uri.
		 * * The resulting string shall *not* be used for display purposes but
		 * for disk operations, like `readFile` et al.
		 *
		 * The *difference* to the {@linkcode Uri.path path}-property is the use of the platform specific
		 * path separator and the handling of UNC paths. The sample below outlines the difference:
		 * ```ts
		 * const u = URI.parse('file://server/c$/folder/file.txt')
		 * u.authority === 'server'
		 * u.path === '/c$/folder/file.txt'
		 * u.fsPath === '\\server\c$\folder\file.txt'
		 * ```
