title: How do I fix an App Service deployment failure for lack of disk space when there is plenty?
body: <p>I have a React web app in VS Code and I have the Azure App Service extension installed. I have used this to deploy my app several months ago successfully. But now when I click the up arrow icon  the deployment starts, runs for a few minutes and then fails telling me that there is not enough space on the disk. Looking at the output messages, I see it is using the D: disk which is an external USB drive with 1.69 TB free of 1.81TB. So why this failure?</p>
  <p>An earlier version of the web app (acestrader.com)is hosted on Azure now from a prior deployment using the same Azure extension from VS Code. I don't think it used the D: drive since that is not plugged in most of the time.</p>
  <p>The Output Messages:</p>

  <p>What do I do to fix this?</p>
