Cleaning the database
This option is used to physically remove database records which have been identified by the system as erased. Most of these records relate to cards and are kept in the Deleted Components section of the database. Using this option considerably reduces the space required by your database. It also improves system performance relating to searches for card information. It does not affect the table Registry, nor does it have an impact on historical reports.
Note: You must back-up the database before
performing this operation. Cleaning the database suspends operation of the database
while cleaning is in effect.
