[mapserver-users] Is there still a 2GB size limit on shapefiles?

[Stephen Woodbridge]

In general the shapefile spec is owned by ERSI and unless they change 
the spec you will have a problem. Last I knew, there are 
pointers/offsets inside the shapefile that are only 32bits wide per the 
spec. it is because of these that you are limited to 2GB.

At some point I thought Frank W or someone was working on a version of 
shapelib that could support greater than 2GB, but only programs that 
used that version would be able to read/write these larger files. I have 
not heard anything on that front in a while so I don't know if that was 
just talk, or code ever materialized.
