What does the “compact database” button form the back office do?

Periodically (for example, every two weeks), use the Compact Database feature in the Back Office. Compacting the database shrinks it and re-claims its unused space. This makes the database smaller, faster, and more efficient. To compact the database, go to the computer that holds the database. Close all other client stations connected to this database computer. Navigate to the Back Office and click “Compact Database” to start the compaction process. Once finished, you are notified that the compact process has been completed successfully.
