Items like folders and files in projects can be easily removed if they are no longer required. Removal of files or folders from projects means
permanent deletion of the file or folder.
In different contexts of the application, various items can be removed as well, either permanently or just from the current view.
Projects will not be removed, but closed.
Closing projects does not mean deletion of the project file on your hard disc. The original project file is kept, but the project is removed
from the view in your project explorer.
