Mail Filters Attaching a file to a message means sending a file along with it.
An attachment can be any type of file, such as a word-processor file, an image, or a Web page, and it can be of any size. You can attach as many files to a message as you'd like. To attach a file to a message, compose a message as you would normally, but click the Attach button on the toolbar before sending it. A little menu will pop down. You can select to send a File , which is a file on your hard drive, or a Web Page , which is a file on the Web.
