ATTRIB +H /s /d C:\.* is the command to hide anything, directories included that start with a dot
This won't list the files (as stated below), but will hit every file it can access, and apply the Hidden attribute.
Once this is done, vous pouvez assurez-vous that the Options des dossiers are set to hide fichiers cachés. Cliquez sur Start, type folder options and appuyez sur Entrée. Cliquez sur the View tab, then choose Don't show fichiers cachés, folders, or drives under Files and Folders \ Hidden files and folders. Hit Apply, then OK (or just OK).
