The 'core' file is a copy of the memory the program was using when it exited. You can use it for debugging purposes - to find out exactly why the program quit, and what it was doing (roughly) at the time... There not for the faint hearted though, and can be very complex... Look up the man page for 'gdb'... You can safely delete them... Regards, Karl Pielorz To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
