Voici une mega liste des extensions PC (2 305), vous donnant leurs logiciels d'origine.
Dans votre navigateur, faites Pomme + F pour écrire l'extension que vous cherchez, c'est plus rapide que de faire défiler la liste.
Cela peut permettre de savoir quel type de logiciel a crée le fichier PC que vous avez, et d'essayer de l'ouvrir avec un logiciel de même type sur Mac. Mais malheureusement ça ne marche pas à tous les coups...
Vous allez ricaner, j'ai des collègues Windaubiens, qui se servent de cet page, où va le monde, madame Michu?
