PokerTracker 3 allows you to delete ("Purge") sessions from the database.
WARNING - Purging is an irreversible process. Anything purged from your database cannot be recovered so we advise you to make a backup of your database before you start.
See the Tutorial: Backup and Restore for more information.
Note:You cannot delete individual hands or players because each hand involves multiple players and affects the session totals. The smallest 'unit' you can purge is a session.
To open the Selective Export window use the PT3 menu Database -> Database Management.
On the Database Management window, select the database you want to Purge from, and click the Purge... button.
This will open the Selective Purge window.
In this window there are several different ways to select which sessions are purged.
