Any IntelliJ IDEA project created in the file-based format can be easily converted into the directory-based format, which is more convenient when project settings are frequently modified by the team members.
On the main menu, choose
IntelliJ IDEA converts the project configuration files and then reopens the project.
- Specify whether you want to open the project in a new window.
When the project is opened, all the project settings are stored in the .xml files in the .idea folder, and it is now safe to delete the .ipr and the .iws files.
