title: What is the difference between Copy Files vs Publish Artifact task in VSTS?
body: <p>In my <code>Copy Files</code> task, I am copying the required files to the file share location from which I will be doing the deployment. What is the use of publishing artifact step? Or it is obsolete in my case. I am confused about the what values should be put in the boxes. </p>
