importing .LAS datasets (LIDAR)

Hello,

I have a number of .LAS files, but ArcMap is not seeing them when I go to add them. The file type (in the normal windows view)
shows it to be the .las extension but type 'DWG TrueView Layer State'. This is my work laptop and I also have TrueView, and I think somehow TrueView added the association. I downloaded the files from opentopography.org

How can I change the file type or add it into ArcMap?

Thank you!

ArcMap doesn't support .las directly for display. You have to create a LAS Dataset, then load the .las files into it (using references), then add the LAS Dataset (.lasd file) to ArcMap. Optionally, you can load the .las files into a Mosaic Dataset and add it to ArcMap.

See Using lidar in ArcGIS, What is a LAS Dataset, and Adding lidar data to a mosaic dataset

Best,
