Hi guys, Help me with this task because I don't see any error(bug) and the program on my computer is working properly. If I verify my solution,then i will receive this error message (and a tip): error: "The addFiles method must write the new files as well as all of the old archive's files to the new archive. Then replace the old archive with the new one." tip: "The method must not add a new file to the archive if a file with that name already exists."
