Project / Project Folder Deletion?

Is there a recommended method to delete unwanted Projects without hosing up something else that may point to it as existing? There seems to be no menu item to accomplish this, but if I click on ‘Project Explorer - XXXX.bbp’ it takes me to a Windows Explorer window where the Project folder resides. Can I simply delete it from here without risk of taking something else unintended along with it or creating an error in some database?
Doing it this way would also be deleting files that are in use I think, which generally might be blocked in Windows(?)

As a Mac user, this works for me:

  1. Use the BBM to open a project you don’t intend to delete
  2. Quit BBM
  3. Navigate to workspace folder and delete the project you no longer want
  4. Open BBM and you you should be functional
