Click on the gear icon below the star icon on a project to open the Project Properties panel. If you are inside a project, you can access its properties by clicking on the Settings button at the top right corner of the screen.
Click on Copy Project button.
Select your target Workspace from the drop-down menu.
Click on Yes, copy this project.
Note: You can only copy the projects that you have created.
Projects can't be moved directly into another workspace but copying them and selecting the desired workspace is an alternative solution.
