I am only guessing, but the 3 files could have been placed in the VirtualStore folder. Try a search for Virtualstore, and see if your files are there.
great news, there isn't that kind of issue with Windows 8, 8.1, or with Windows 10. Files go where you direct them to go, and no where else. No such thing as "virtual store." Remember, July 29 is roll out day for Windows 10, and a free upgrade for Windows 7, 8, 8.1, and 10. For XP users, sorry you dip out.
