• Normal reindexing: Classic reindexing (with statistics and without compaction).
• Reindexing with Compaction: Reindexing with compaction (retains only active records. All the crossed or deleted records are permanently deleted).

• The indexes are reorganized by the reindex operation. After the indexing operation, the access to indexes is optimized. The indexing operation may be required if the index file is lost or damaged.
• WDMap allows you to easily reindex a data file. However, to reindex a data file more completely, use the WDOptimizer tool.
• A data file can also be reindexed using Windows Explorer. Simply select the "Optimize" option from the context menu of the data file to be re-indexed. Then, the reindexing is performed by WDOptimizer.
