Contoh
Contoh kode berikut membuat FileSystemTask sebagai Executable dalam paket. Menyalin FileSystemTask folder uji, yang berisi dua subfolder dan file .txt, ke folder lain. Folder dan subfolder yang merupakan folder sumber memiliki atributnya yang diatur ke baca-saja karena Attributes properti diatur ke ReadOnly dalam contoh kode.
