Database Purge

It is recommended that you discard unused GPS data from the database on a periodic basis.

Doing this will assure efficient data processing and program response. In most cases, data

downloaded from your tracking units make up around 85% of the size of your database. Your

database should not reach 1 gigabyte in size or damage to the database structure and/or data will

occur. The size of your database is displayed at the bottom of the Shadow Tracker

program window.

To make sure you are getting the true database size you can at anytime perform a compact on the

database. This will delete unused space and reduce the database down to its smallest size.

If you wish to keep all of your data for future reference, make a copy of your database first and

place it in a safe location. That way, you will always have these records available in the future.

You can later connect to your backup database to view the archived records.

To purge unused data from your database:
