Keterangan

Properti FileName memungkinkan pengirim untuk menyarankan nama yang akan digunakan untuk menyimpan lampiran email di komputer penerima. Nama ini hanya saran; sistem penerima dapat mengabaikannya. Nama tidak boleh menyertakan informasi jalur; informasi tersebut diabaikan oleh komputer penerima.

Untuk menghapus informasi nama file, Anda dapat mengatur properti ini ke null atau string kosong ("").

Header Content-Disposition dijelaskan dalam RFC 2183 tersedia di https://www.ietf.org.
