Overview
WDMap is used to find out whether an HFSQL data file must be reindexed and reindex an HFSQL data file.
Two types of reindex operations are available:
  • Standard reindexing: Standard reindexing (with statistics and without compression).
  • Reindexing with compression: Reindexing with compression (keeps the active records only. All the crossed or deleted records are permanently deleted).
Reminder:
  • The indexes are re-organized 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 file more completely, use WDOptimizer.
  • You can also reindex a file from the Windows explorer. To do so, select "Optimize" in the context menu of the file to reindex. Then, the reindexing is performed by WDOptimizer.
Remark: From version 19, HFSQL is the new name of HyperFileSQL.
