An attachment is a file that you can include as part of your email message. You can attach all types of files to your message, including word processor or spreadsheet documents, audio files, image files (.bmp, .jpg, .gif, etc.), web pages saved as HTML files, and more. You can attach up to 50 files with a maximum message size of 20 MB.

When someone receives your message with the attachment, he can open the file in the file’s native application (the application in which the file was created). He can also save the file locally and, in many cases, can edit the local file.
File attachments provide an easy way to share any type of document. For more information on attaching files to your email see the Working Safely With Email Attachments tutorial.
When you’ve completed your message, you can send it.
