When would you use a file attachment in an email message?

Attachments to email messages can come in many forms: documents, sound files, videos, pictures, programs (some of which may do harm to your computer) and more. The importance of attachments allow email users to send along a referenced document for review and improvement. Attachments to email messages can vary in sizes and some servers and accounts have permissions established that control exactly how large attachments can be to email messages. Attachments can suck up quite a bit of bandwith sending and receiving and then they have to be stored somewhere, too. A Word of advice, never open an email attachment from an unknown source. At the very least, have virus protection with the most current definitions in place to scan them before downloading them onto your computer. The most dangerous files are those ending in .exe (executable files), which go right to work installing themselves with a simple double-click. Happy emailing! Sending pictures, documents, encrypting data for secure transmission, some businesses use it to order product.
