C: drive gets full on IIS server

I came across two scenarios where the C: drive gets completely full on a IIS server. I suspected the log file folder first, but it turned out to be something else hidden.

  • Scenario 1: I ran a warmup script that uses an instance of IE to fully mimics a full page load of web applications, not just page hit.
  • Scenario 2: I set up an IIS server as a dedicated SharePoint provider-hosted on-prem web server. Over time, the C: drive was getting full. Warmup script used to run for a while on this server. 
In both cases, the following folder was the culprit. When using an instance of IE, it probably used this folder for caching.
