Introduction to Attachments Text is not the only kind of data you can transmit in an email message. If you are a Juno member, you can also send pictures, word processing documents, spreadsheets, audio clips, video clips, programs, or any other type of computer file by "attaching" the file to your message. Similarly, you can receive any type of computer file from others who send you messages with attached files. "Attachments" are specially encoded so that when they arrive at the destination computer, they can be opened by the same program that was used to create them. Because attachments are generally larger than plain text files, Juno cannot afford to provide the file attachment feature as part of its Free email service. If you would like to send and receive file attachments, however, you can sign up for Juno Platinum. Before you send or open an attachment, you should know these facts:
File attachments may contain viruses. Because a file attachment does not just contain text, there is a risk that it may be infected with a destructive type of program called a virus. Simply receiving an infected file, or even saving it on your computer without opening it is not dangerous in itself, but you may want to check attached files with antivirus software before you open them. Both the sender and the recipient need to have a program which can read the attached file. Attachments are opened by other programs on your computer, not by your email software. This allows people to send and receive many kinds of files, like word processor documents, videos, and sounds, but it means that you need to have the program that created the file-or a program that can view files of that type-on your computer.For example, if you are sending a document created by the latest version of Microsoft Word and your recipient is using an old version of WordPerfect, he or she may not be able to read your document. In such cases, try to convert your file to a format your recipient can handle before sending the file. The recipient needs to be able to receive attachments. For example, if the person is using Juno's Free email service, he or she will not be able to receive your file attachments. File attachments are bigger than most regular email messages and they take longer to send and receive. Receiving a long file can take several minutes, which is both time-consuming and, if you are paying for an online connection on an hourly basis, costly. In addition, a file consumes resources by taking up a computer's hard disk space. Therefore, send files only to people who you are reasonably sure will appreciate receiving them. Juno can only accept file attachments in the MIME format. The modern standard for handling attached files is called the 'MIME' format, and that is what Juno uses. However, some email systems still use an older standard called 'Uuencoding.' If your recipient experiences trouble viewing your files, and you are both using the same program to open the file, then find out whether your recipient's email system supports MIME. Conversely, if someone sent you an attachment but you only see garbled text, the message was probably sent in an older format rather than in MIME.
