Opening, Reopening and Closing Projects
On this page:
IntelliJ IDEA allows opening several projects simultaneously in different windows. By default, each time you open a project while another one is opened, IntelliJ IDEA prompts you to choose whether to open the project in the same window or in a new window. If necessary, you can change this behavior using controls on the System Settings page.
In the Project Opening section of the System Settings page, choose one of the following options:
- Open project in a new window to open a new IntelliJ IDEA window each time a new project is opened.
- Open project in the same window to stay in the same IntelliJ IDEA window.
- Confirm window to open project in to keep the default behavior and display a dialog box to choose how to open each new project.
