Make sure that one of the options Open project in a new window or Confirm window to open project in in the General page of the Settings dialog is selected.
Opening multiple projects
Open a project, while another one is already opened. PyCharm
prompts you to select whether you want to open the project in a new window, or reuse the existing window.
- Do one of the following:
- Click Open in new window button to leave the current project in its window and open the new one in a separate window.
- Click Open in current window, and select the check box Add to currently opened projects.
Clicking Open in current window without selecting the check box Add to currently opened projects results in closing the current project and opening the new one in the same window.
- When reopening, PyCharm suggests to reopen the whole group of projects.
- The check box Add to currently opened projects appears when you open a new project in a window, where another project is already opened.
