I accidentally made the entire PHPstormProjects folder, which contains all of my projects, and turned it into a project. When I realized my mistake, I deleted all the files which I had uploaded into the project, but it still lists it as a PHPStorm Project.
I don't want to simply delete the project, as it contains all of my other projects. Is there any way to 'unset' a PHP project?
On "Welcome" screen (when all projects are closed) just select unwanted project and press Del key.
To make sure that IDE will not treat this folder as a Project -- just delete project settings (.idea subfolder) when that project is closed.
