Hunter Killer revisited

Hunter Killer is a utility to delete old files. For years it has worked fine just deleting files more than a specified number of days old. Now I have extended it to be able to delete files that are hours old, or to keep a specified number of recent files.
You can visit the Hunter Killer page to learn more. I have not updated the screen shots yet, and will do this after implementing a "run application" feature. It has been an interesting exercise looking at software that is 4 years old, and trying to remember how it works. That's where comments are so useful. I have also had to implement a quick sort routine, so I had to get out some dusty old programming books to remember how it works.
