While composing a mail, you attach an item from your desktop and send it to your friend so he can use that item.

Welcome to the forum spider2k7! :wave:
Depends on what the item is. Is it a program or something along the lines of a program?

That would depend on what the item was spidey2k7 and where abouts in the world you are. If you decided you were going to try and send music for example, you might find that you are breaking the law (although there will only be you and the recipient who knows )

Yup I agree what was said above. Depends on the copyrights of the item.
