you might try opening the db that holds the tables, and *export* them to the
other db. a message should come up asking if you want to overwrite, for each
duplicate table name. note: if there are relationships set up for the
tables in the destination database, Access may not allow an overwrite
(you'll just have to try it and see).
in that case, you might want to open the destination db, link in the tables
from the other db, delete the records from the native tables in the
destination db, and then append the data from the linked tables into the
destination tables.
