I would like to inform friends that yesterday I uploaded a Folder to google drive through Chrome. When the message popped up that folder uploaded successfully. I signed out and switched off PC. Today when I checked Google drive, that folder was nowhere and even some other photos(not all) which were earlier uploaded were missing. I checked activity but there was no activity in yesterday date. Can some one explain. But with this happening, my advise to friends is that never sync their file or folders with any Drive. Some day they can loose these from both locations. Instead manually upload. So that if any thing bad happens, it will effect only one side.
