The C-N Checkbook™ program will always use the files that are in the "Blank" folder that is inside the "Files" folder in the same folder with the program. If not present C-N Checkbook will create a new set. If you have the program asking for a password and no matter what you try it is wrong then the correct folder has been moved or renamed. (Do not panic if this happens, just enter any password 6 times and C-N Checkbook will put you back to the desktop after 6 wrong passwords.)
The files that will open when you first start up C-N Checkbook are sample files that give yo some examples of how different types of transactions should be handled. Look them over.
