L'instruction \c;open();\n; ouvre un fichier de texte dans le dossier files/. Cette instruction est une méthode de la classe \c;\l;file\u cbot\file;\n;. C'est la raison pour laquelle on n'écrit jamais \c;open()\n; tout seul, mais \c;handle.open()\n;:
Files can only be created and opened in the files/ folder which is located in the folder where Colobot has been installed. You cannot not create or open files that are located elsewhere than in the files/ folder.
