Recovering an Accidentally Deleted File

Have you ever accidentally deleted the entire folder for one of your avatars once? I have! And luckily, despite what Unity tells you, if you accidentally delete a file in the editor. It's still possible to recover it, the catch is that you can (probably) only recover files that you've just deleted. Sorry if you were hoping to get that file back you accidentally deleted a week ago. This probably may only work on windows too. It does definitely work in my case, I've had to do this an embarrassingly large amount of times.

What?? How do I do this?

Whenever you accidentally delete a file, you can right click in the project window where you deleted it and right click in the empty space and click "Undo Delete" and woah! It's back! Crazy right? If that doesn't work, check the trash bin on your computer.
