Restoring Blank Shortcuts on a Hard Disk?

I just recently added this old hard disk that was found in my house and that was a back-up disk for our Internet Cafe. It had so many files and among them were games. Sadly, I cannot open those games since they are blank shortcuts. The original file for that game was gone. How can I restore them?

These are old games (e.g. Command and Conquer Generals, Medal Of Honor Breakthrough, etc.).
