Bidang

AllDirectories	1	Menyertakan direktori saat ini dan semua subdirektorinya dalam operasi pencarian. Opsi ini mencakup titik reparse seperti drive yang dipasang dan tautan simbolis dalam pencarian.
TopDirectoryOnly	0	Hanya menyertakan direktori saat ini dalam operasi pencarian.

Contoh

Contoh berikut mencantumkan semua direktori dan file yang dimulai dengan huruf "c", seperti dalam "c:\". Dalam contoh ini, TopDirectoryOnly digunakan untuk menentukan bahwa hanya direktori tingkat atas yang harus dicari.

using namespace System::IO;
