Hi, have you ever accidentally deleted your single player worlds? I know I have, and I now know a way to recover them. (For Windows 7 and Vista Only!)

Step 1: Press Start, go to run, and type in "%appdata%" (Without the quotation marks.)



Step 2: Open your ".minecraft" folder.



Step 3: Go to your "saves" folder.



Step 4: Right-click and go to "Properties"



Step 5: Go to "Previous Versions" and click on the time/date you would like to go back to, and then click "Restore"



Hope i have helped you recover your saves. Please Diamond!

Thank you everyone for all the diamonds this tutorial has been getting! I'm so glad i helped all these people!
