look up the Import Records feature in the on line help system. This powerful little tool can move large blocks of data and (if you so choose) the actual table definition itself from one file to another. There are lots of different options for how to use this tool, so I suggest doing a little reading and experimenting then check back here with any questions.
Since this tool can make major changes to your file, keep back up copies of all your files.
I have downloaded Bento 2. It is more my speed. I'll learn some database skills with it before jumping in over my head....Thanks
