How to make Windows eat your file with a simple accident

Well, I just lost my backup of a file because I hit the wrong key on accident.

How to reproduce:

1) Ctrl-C a file to your desktop.

2) Edit the source file and save it

(Make sure you haven't changed the contents of your clipboard)

3) Hit ctrl-x on your backup

4) Hit ctrl-z (I accidentally hit x and z at the same time)

5) Your backup is now gone forever!

6) Check your source and you see it hasn't even been overwritten or anything. It just disappeared.

I think from now on I will always just copy and paste instead.
