WDOptimizer The different operations that can be performed with WDOptimizer are as follows: - Optimizing the indexes
This option allows you to perform several types of operations:- Check the indexes: Checks the consistency between the index and the data files.
- Optimize speed of indexes (Re-calculate statistics): Optimizes the indexes by calculating statistics on the indexes. These statistics are used to optimize the filters, the queries and the HFSQL views.

All the crossed records are automatically deleted.
