understanding merge
I'm trying to use merge to eliminate duplicate master images between multiple Libraries but it doesn't seem to work.
In my master Library (A) I move all the photos from a year into a Project entitle with the year (2010)
I do the same in Library B; (2010).
I then export that project from Library B; (2010).
I then import that Library (2010) into my Master Library A.
The Master Library has a Project in it entitled 2010. The imported Library has a Project in it entitled (2010) but they are not merged. It simply imports the Library and creates a 2nd Project entitled 2010 (1).
What am I not understanding about the merge function?
