Πρόσθεσα 5 γραμμές με σχόλια για να δεις πως μπορείς να το δουλέψεις. Δοκίμασε να εκτελέσεις μία μία τις γραμμές αφήνοντας κάθε φορά τις υπόλοιπες σαν σχόλια και παρατήρησε τι συμβαίνει στα δύο αρχεία.
Δημιουργεί στον κατάλογο από όπου εκτελείται το πρόγραμμα τα αρχεία "all_files.txt" και "open_files.txt" τα οποία περιέχουν τα ονόματα όλων ή των ανοιχτών μόνο φακέλων αντίστοιχα.
