IntelliJ - Delete a project

It is unbelievable that I have to search the internet to find out how to delete an IntelliJ project. The answer is you can't delete a project from IntelliJ. You have to do it manually using another application such as File Explorer, Command line, etc.

Here is how to cleanly delete an IntelliJ project.

1. Open the project that you want to delete.
2. Navigate to File > Invalidate Caches / Restart... and Invalidate the cache. Otherwise, recreating a project with the same name will cause other errors.
   
3. File > Close project.
4. Click on the X to remove your project from the project list.
   
5. Manually use another application to delete the project, such as File Explorer, Command line, etc.
