[Plugin: Contact Form 7] Upload files not working – How to ?

I create a File upload tag that its required.
Name: Screen

In the form I have: [file* Screen]

In the message body I have: [Screen]

Whats needed in the File attachments of the Mail section ?

[your-file] is not working.
[file-Screen] is not working.

I just receive the name of the image, but not the image itself. Whats the correct way to do it ?

Thanks.
