Attachments are. . .
You can attach files to your messages in most of the current email setups. This simply means you're able to send things like word processor documents, presentation slides, spreadsheets, or even webpages, attached to any message you create. The great thing about attachments is that you can store all those important documents that you get sent electronically, rather than on dusty shelves, and will be able to open them up and work on them. Do remember to back up everything though if you're going for the paperless office. And, of course, the recipient has to have a copy of the right application their end in order to be able to see what you've sent them.
