title: How to open an existing project in Eclipse?
body: <p>I have just created several project using Eclipse. Now restart Eclipse and want to see one of the projects. How can I do it?</p>
  
  <p>I have tried File -> Import -> General -> Existing Project into Workspace.</p>
  
  <p>Then I select the directory of the project that I want to work on and, as a result, I get an error message: "Some projects cannot be imported because they already exist in the workspace".</p>
  
  <p>So, it looks like that I do not need to import a project, because they are already in the workspace... But how I can "see" the projects that are in the workspace? If I create a new project, I see it as well as all other existing projects but I do not want to create a new project just to see the existing projects.</p>
