Hi, I have done a script that contains with open (‘file.txt’, ‘w’) as fh: fh.write(‘blabla1’) afterwards I do, with open (‘FILE.txt’, ‘w’) as fh: fh.write(‘blabla2’) the result is a file called ‘file.txt’ that contains blabla2 I think that the name of the file is not case sensitive and I think that it should be. Thanks a lot, Natàlia
