Definition: A file attached to an email message as an enclosure. It sends as a duplicate of the original file, and is a superior alternative to faxing. It can be of any type of software file, and can be opened by the receiver if that person has the appropriate software to view the file attachment.
File attachments are cousins to "downloaded" and "uploaded" files. The main difference is that attachments are shipped to a specific receiver via email, while downloads and uploads are less discriminating with whom they convey files to.
Also Known As: "File attachment" or "enclosure"
