Microsoft Access Developer Question:

Size limitation does not pertain to number of records in a table within a database. Forms, reports, macros, and modules also contribute to database size, but is rather minimal compared to tables containing records. It is recommended that if large amounts of data will be maintained or constantly deleted and new data imported, put your tables in another database and link the tables back into the main database. The utilities for database compression and repair will run much more quickly. In Access 2.0 databases the byte size limitation is 1 gigabyte. In general, use the 1gb rule and suggestions here to maintain performance of the database. See also "How Replication Increases Size of Database.".
