Açıklamalar

Bu yöntem, örneğin, c:\mydir öğesini c:\public'a taşımayı denerseniz ve c:\public zaten mevcutsa bir IOException durum oluşturur. Parametre olarak destDirName "c:\\public\\\mydir" değerini belirtmeniz veya "c:\\newdir" gibi yeni bir dizin adı belirtmeniz gerekir.

Bu yöntem, bir dizinin salt okunur bir dizine taşınmasına izin verir. Hiçbir dizinin okuma/yazma özniteliği etkilenmez.
