Global Mapper v25.0

View Shed temp file location

Hello,

I am totally new to global mapper and I am trying to use the view shed tool to place multiple radio towers across 800 sq miles.
I have used our Lidar data to "create elevation grid from 3D vector data" I actually "created a new map Catalog" with the data since there was so many files.

When I place one view shed I get the following error. 

Error calculating view shed.
Out of space trying to create grid of size 383,033,366,160 [306,170 x 312,762 elements of size 4.
Not enough disk space (111,404 MB) for temporary file of size 365,289 MB in folder C:\TEMP\GlobalMapper\
Is the drive with your temp folder (either system or override for Global Mapper) full?

Both memory allocation and temporary file allocation failed.
SmartGrid.cpp - 221
Version: v16.2.6 (64-bit)
Build Time: Sep  6 2015 15:50:06

Is there away to change the temp location where the view shed is placed?

Like I said I am very new to this product and I hope all this makes sense.

Thanks,
Julie
