Bonjour,
j'aimerai exécuter une commande Dos qui efface tous les fichiers *.doc d'un répertoire, avec mon programme Java, mais après un bon nombre de tentatives, cela ne fonctionne toujours pas. Est-ce que quelqu'un pourrait m'aider?

J'ai essayé ceci:

Process processDelDoc = Runtime.getRuntime().exec(new String[] {"cmd.exe", "/c", "del U:/MyUrl/MyFolder/*.doc"});

qui ne fait absolument rien (ni erreur, ni supression ), et ceci:

Process processDelDoc = Runtime.getRuntime().exec("del U:/MyUrl/MyFolder/*.doc");

qui me créé cette erreur:


java.io.IOException: CreateProcess: del U:/MyUrl/MyFolder/*.doc error=2
