This article is part of a ‘mini series’ about hidden gems, tips and tricks around Eclipse.
The topic of this one is how to efficiently open and close projects.

Projects in the Project Explorer

I have usually in my Eclipse workspace many, many projects. To keep all projects open is not a good practice (uses more memory on the host and can slow down things). So usually I have projects closed which I’m not working on. To close all other projects except that only one I use the ‘Close Unrelated Project’ context menu:

Close Unrelated Projects

That way all other projects get closed.

To open a project, the simplest way is to double-click on a project:

Open Project with Double-Click

Another way is to select one or multiple projects and use the context menu:

Open Multiple Projects

Happy Opening 🙂
