Filenames gone in WinExplr

Just recently I've noticed many filenames are no longer listing in WindowsExplorer.

Hmm?

I know I have golf courses in my 'Courses' folder and have seen them there for years until now.

I have no idea what happened to them except that I tried Carbonite and didn't like it and uninstalled it.

I'm thinking when Carbonite took their green,yellow,red dots they took the filenames with them, somehow.

Is there another reason for the filenames disappearing?
Any help is much appreciated.

Thanks,
