Not enough temporary storage ESRI warning 100648

[EdgarGuerron_Orejuela]

Good morning everyone,

I am trying to use the Euclidean distance and Distance accumulation tools, but every time I try running this it looks like it is working but after hours of running I get the following warning message: "100648: 637,214 MB of temporary storage is estimated to be needed. 303,879 MB of storage is currently available" (see image below).  

Any guidance to solve this issue is greatly appreciated.

I am using ArcGIS Pro 3.3.1. 

My computer has 2 SSD drives, on is 500GB the other one is 4 TB. I have 120GB of RAM.

Your E drive... is it the one with most storage?

Use the environments tab to specify where scratch data is to be directed, that is the one that needs to have space for temporary data.
