I have a Logitech mouse. I often maximize my applications in OS X. E.g. I will have Evernote running on one Desktop and Google Chrome running on another, both in full screen mode.
Suppose I have a file in my Downloads folder. How do I attach it into Evernote using drag and drop? Or similarly, how do I attach it to an email using drag and drop. On Windows, drag and drop is made simple by the fact that you can easily resize windows. But, with OS X, since all your windows are maximized, or at least that is how I have them, how do I drag stuff from one place to another?
P.S. I have a simple USB mouse, I am not using Apple trackpad or any such fancy thing.
