Missing .exe files

After finishing GTA: Chinatown Wars, I went to play the original Grand Theft Auto. I keep in a folder called “Program & Games,” which is where I store all my games that don’t need to be installed. In other words, this folder can just be moved to another computer if I get a new one. Anyways, i couldn’t find the .exe, so I looked at a few other games I had in there. No .exe’s. None. I did a search in the folder and all subfolders, and there isn’t a single .exe in there. What happened? I could have run a script that deletes them all, but I don’t think I’d do that. Also, if every .exe was infected with a virus, I suppose they could have been quarantined. I think I would have noticed either occurrence, but I don’t have any other explanation.
