I don\'t see any menu item I can use to create a new workspace.
What should I use to create a new workspace and move some of the projects from existing default work
You can create multiple workspaces in Eclipse. You have to just specify the path of the workspace during Eclipse startup. You can even switch workspaces via File→Switch workspace.
You can then import project to your workspace, copy paste project to your new workspace folder, then
File→Import→Existing project in to workspace→select project.
