Microsoft confirmed it has fixed a bug in its online file storage and sharing service Windows Live FolderShare after users reported problems that the service was deleting files without user authorization. Microsoft sent an e-mail to users Friday alerting them that it has fixed a bug that may have "accidentally moved" user files from their original folders into the FolderShare Trash folder, and that users should not delete files in Trash until they ensure they were meant to be deleted. It also advised users how to retrieve deleted files from the Trash folder. A copy of the information sent to users has been posted on the FolderShare Web site.
