I have a 1.7 million record feature class that I need to export to a shp file. When I run feature class to feature class/feature class to shp file the shp file has less than half of the points (470,000) loaded. What is the workaround?
Hmmm...shapefiles are limited to 2 GB in size so I wonder if you're hitting the storage limit perhaps? And this information about limitations as well.
It's the very first hit and an almost identical question in the "Related" bar...
Looks like shapefile limitation.
an ugly alternative, depending where it needs to be used
