Tell me if I've got this right. I just bought Legacy and am creating gedcom files from my Access database. Because I have so much data in Access I'm creating the gedcom file piecemeal and trying to load little by little. I take it that the first file I import with people loads those people. But if I want to load additional information for the existing people in my tree I have to create a whole new family file and reload the people again with all info. A second or third gedcom file won't add info to an existing entry. I did this and all the people were duplicated as new entries.
So that tells me that getting gedcom files from other places only gets you new people with any info included with them. Right?
