Hello, Chip.

Finished Mac applications have a Help menu which is the last word on the right in your menu bar, before the icons start.  BookMacster's looks like this…



You see that the top item is BookMacster's Help Book.  There are other resources below that.

BookMacster's Help Book is also available on the internet, at this link.

Let us know what you want BookMacster to do, and we'll review whether or not it's configured correctly.

The instructions for finding and deleting duplicates are in this section.  We also have a short screencast on that subject.  The actual finding and deleting of duplicates starts at about the half-way point :40 seconds from the start.
