I have a shapefile of land surface altitude points created from a DEM. The problem is, there are about 7.6 million points and I need to move it out of ARCMap and to another program and it's too large for the second program. Is there a way to select every 10th point in the shapefile and create another shapefile?

If you just want to select every 10th point regardless of its spatial relation, you could just use the select by attributes with a unique id field:

mod("FID",10)=0

where FID is your sequential integer id field
