How to Restore a File That Was Replaced and Saved Over
Mistakes are commonplace when it comes to computers, and one of the biggest computer-related blunders is accidentally overwriting a file.

Click on the "Start" menu and select "Search."
Choose the option to search for "All Files and Folders."
Type in the name of the overwritten file and press the "Search" button.
Right-click on the file and select the "Properties" option.
Select the "Previous Versions" tab and select the version of the file which you wish to restore from the menu onscreen.
Click on the "Restore" button.
