When you do the compressed archive test (Shift + Alt + F9), it pops up a message box only if the archive is damaged. But, I think it should also inform the user if everything goes well at the end (of course, with MB_ICONINFORMATION icon, not with error/exclamation).
Because sometimes when I'm very tired at work, I can "forget" if I actually have issued a command or not, if there's no explicit feedback from the program
