How can I "reload" my deleted scenes folder?!

I accidently deleted all my scenes which were in a folder called “Scenes”. I only wanted to delete a single scene but…you know. Please help me! My whole game is gone and I don’t want to make it from scratch again.

Thank you in advance!

P.S.: I didn’t make a backup. Yeah, I know that was not a good idea.

Well, you could look in your system’s recycle bin/trash folder, just as you would for any other file that you delete from your system. If it’s not there and you didn’t take a backup, it’s gone. Learn to take backups or, even better, use source control.
