About the methods i use in the application along with file.delete() (which

file.getName();
file.lastModified()
Path path = Paths.get(fileName);
Would any of these cause the lock on the file ?Le dim. 9 oct. 2022 à 16:03, Thomas Hoffmann (Speed4Trade GmbH) <thomas.hoffm...@speed4trade.com.invalid> a écrit : > > > -----Ursprüngliche Nachricht----- > > Von: Martin Moore <martinmoore...@gmail.com> > > Gesendet: Sonntag, 9.
