An attachment is a file attached to an email message. Many email systems support sending text files as email. If the attachment is a binary file or formatted text file (such as an MS-Word document), it must be encoded before it is sent and decoded once it is received. There are a number of encoding schemes, the two most prevalent being Uuencode and MIME.
