I have a database of publications with publisher subdirectories and issue sub-subdirectories on my desktop computer. I have duplicated this on Dropbox. When I add a new issue to my destop subdirectory, I must locate the specific database and publisher in Dropbox to put the new issue in the right place. Is there a way for Dropbox to know when I add to the desktop database and automatically sync the new file to the Dropbox subdirectory? I don't want to sync pictures, just zip files.
