I have multi boot Windows. While in Windows 8 I tried to access the documents folder in Windows 7. I do not know what happened. I may have pressed some wrong key on the keyboard but that folder vanished for a while. Later on it was visible but nearly all my files in the Documents folder of Windows 7 are not visible whether accessing from Windows 7 or from Windows 8. I do a search of the files stored in that Document folder but with no result. How to access the files again?
