Phil, there is no point in doing both PACK and a ZAP. Once you have zapped, there are no records left to pack.

Hi Mike,
Of course you're right, haven't zapped for ages.
Only pack after deleting a few records.

Regards,
Phil

Hello,

as far as I know zap is much faster.
Both (zap or delete all + pack) need exclusive access.

RE: How to delete all records in a DBF - Visual Fox Pro

Your're right, Tom. PACK is the slowest because it involves copying all the records in the table, deleted or otherwise. With ZAP, VFP simply has to change one field in the table header.
