title: FileNotFoundException: "Access is denied" when loading data from .txt file
body: <p>I wrote a simple program that reads and parses text data from a .txt file. It works great at my work PC, but on my home PC, even with the filepath updated, I'm getting the following error:</p>
  
  <pre><code>java.io.FileNotFoundException: C:\Users\scien\IdeaProjects\teambuilder (Access is denied)
  </code></pre>
  
  <p>And the stack trace reads as follows:</p>
  
  <pre><code>    java.io.FileNotFoundException: C:\Users\scien\IdeaProjects\teambuilder (Access is denied)

  <p>I have ensured that the filepath is correct locally and I've run IntelliJ as an Administrator. I am the admin of this PC so there should be no permissions problems. I've also looked at the other SO posts and they either concern WildFly or other addons, or the questions have gone totally unanswered.</p>
  
  <p>What should I do?</p>
