Copier le fichier dans le dossier de l'utilisateur avec une ligne de commande

Nous utilisons des barres obliques inverses pour les chemins. Slash est un interrupteur et la barre oblique inverse est séparateur de chemin.

Utilisation %userprofile%\desktop. Si le chemin d'accès est susceptible d'avoir des espaces, placez-le entre guillemets.

copy c:\windows\win.ini "%userprofile%\desktop\*.*"
