Moving a file or folder from one location to another is easy using the keyboard shortcuts. Open Finder and select the source file or folder, then use Cmd-C to copy. In Finder again, go to the new location and use Option-Cmd-V. That will move the folder or file to the new location. No need to have two windows open or to drag and drop. Of course, if you just want to copy the folder or file, use Cmd-V at the target location.
