Trouble opening large 1+gig GeoTiffs

I’m having trouble opening these large mosaics that Pix4D exports.  Is there a trick to getting these to open in programs like AutoCAD?

try importing the tiles seperately or a couple at a time

We can import the titles separately but importing all 144 tiles by hand is tedious and time consuming.

Sort them by extension and shift select a group. I do it in autocad everyday with the mapiinsert command since autocad can not handle large tiffs but qgis can.

Check if your computer have enough ram. My advice is to open the tiles in a GIS software like QGIS or ArcGIS. But i’ve 36GB of ram.
