Quick scanning only affects file systems that use multi-record buffers. See //Database Drivers //for more information. A value of zero (0) disables quick scanning; a non-zero value enables quick scanning. Quick scanning is the normal way to read records for browsing. However, rereading the buffer may provide slightly improved data integrity in some multi-user circumstances at the cost of substantially slower reads. **Implementation:** The **QuickScan** property sets SetQuickScan method, which SENDs the QUICKSCAN driver string to the file driver for each specified file. The QUICKSCAN driver string is supported by the ASCII, BASIC, and DOS drivers.
