I'm using FPD. After I delete a record, do I really need to PACK the database and then REINDEX it, so that my index file will be working again? I have problems when dealing with index file with UNIQUE option. The index file wont' be updated when there're changes in my record, such as adding and deleting. If I really need to REINDEX every time, won't it take very long time if I have 1 million records?
