This morning I realized that notes I had taken on my iPad were not properly syncing with the my notes file on my Macbook. I think this has something to do with the .acc4 extension, which I had overlooked until now. I managed to merge a notes file from my Macbook with another file of the same name plus the .acc4 extension from my iPad. That brought the notes from the iPad in, but it also created the problem of duplicating all the notes the two files already shared. Could someone tell me where I went wrong, whether there is any way to delete duplicate notes, and/or how I should set things up differently?
