All Files Moved To The Root Of Documents?

I have had this happen once before, I am running Windows 8 on an OCZ Vertex 4 SSD.The problem is that suddenly all my files inside all the directories and sub directories in my Documents folder have been moved to the root of Documents and have all been named with their original directory location in the filename. To give a clear example: a file originally located in Rockstar GamesL.A. Noiresettings.ini is now in my root Documents folder under the name Rockstar Games_L.A. Noire_settings.ini

All of the folders and sub-folders in my Documents are empty and all of the files are in Documents with those names. They all follow the pattern of having the directory in the filename separated by underscores . I have over 11K files now sitting in my Documents and all my programs that require files in my Documents folder are now broken.
