How do i delete my projects

I Am working on this game
and i just restarted it and for some reason i have like 10 folders and there all the same game just different maps (From when i was just messing around ,and didnt get the whole game)
But now i get it and i want to delete all of them without deleting Unity it’s self
(Which i did like 40 minutes ago!!!)
Thanks Be sure to check out my game ,Stranded when im done (Not official name)

EDIT:When i go into File>open project theres like 10 of them there How do i delete them

If you’re trying to get rid of some directories within your project’s assets folder, you should be able to do that directly from the editor using the project view.

If you’re trying to delete an entire project, you should find the folder containing the project and delete it from your system – just be sure that’s actually what you want to do!
