Ich brauche ein Programm, um die Datei zu überschreiben, aber manchmal ist ein Prozess gesperrt es. Wie überprüft man, welcher Prozess eine Datei sperrt und wie man sie entsperrt? Welche Funktionen sollte ich verwenden?Welches Programm sperrt die Datei
Ich habe im Internet einen solchen Code gefunden, aber es geht mir nicht.

das klingt wie Sie jemand den Job für Sie tun möchten !! Suche nach "überprüfe, ob die Datei benutzt wird" oder ähnliche Begriffe auf Google, ich bin mir sicher, dass du genug Informationen finden wirst ... – ComputerSaysNo
