Hi Sasidhar

Maximum size for MAP file is 2 GB and maximum size for DAT file is 2 GB.
Whichever you hit first will limit your layer size. If you have a lot of
data attribution you may fill DAT first. If not you might fill MAP (
geometry ) first.

One way round the problem is to use MapInfo seamless layers. Break your
area of interest down into smaller rectangles. For example if your 15
million records cover 1000 km x 1000 km split into 100 squares of 100 km
x 100 km. Then create a seamless layer over the 100 base tables.

Regards


Bob
