Açıklamalar

Bu yöntemden döndürülen dizinin, dosya ve dizin adlarında geçersiz olan karakter kümesinin tamamını içermesi garanti değildir. Geçersiz karakterlerin tam kümesi dosya sistemine göre farklılık gösterebilir. Örneğin, Windows tabanlı masaüstü platformlarında geçersiz yol karakterleri ASCII/Unicode karakterlerinin yanı sıra 1 ile 31 arasında tırnak ("), küçüktür (<), büyüktür (>), kanal (|), geri al (\b), null (\0) ve sekme (\t) içerebilir.
