I was recently helping somebody move their Mac's information to Google Drive, and the best solution turned out to be using the Google Drive client for Mac. I moved the relevant files to their Google Drive volume in Finder, then created a few aliases from some folders inside Drive back to the Desktop.
We discovered a small issue when attempting to drag files into the folder aliases: Files will copy, as opposed to move to the destination. The person that I was helping is accustomed to the behavior of a real folder, where files move into a folder when they're dragged on top of it. I believe that this is because the alias refers to a folder on a (technically) removable volume, so the alias is treated the same way as a removable USB drive would be.
Is there a way to configure Finder so that it will prefer to move files when dragging them to external volumes, as opposed to creating a copy? I specifically want to find a way to make this happen automatically, as opposed to using keyboard shortcuts.
