title: How to fix: "The file is too large: __ , showing a read-only preview of the first: __" in Intellij IDEA?
body: <p>I am trying to view a large file in Intellij IDEA, but I am coming across the error: "The file is too large: 30.1 MB, showing a read-only preview of the first 2.56 MB".  </p>
  
  <p>I have seen some previous answers to this question including: </p>
  
  <p><a href="https://stackoverflow.com/questions/45681019/intellij-cant-display-big-file">IntelliJ can&#39;t display big file?</a></p>
  
  <p><a href="https://stackoverflow.com/questions/14010524/intellij-idea-12-java-file-is-too-large-for-editor">IntelliJ Idea 12 - Java file is too large for editor</a></p>
  
  <p>The issue is that I cannot find a idea.max.intellisense.filesize or idea.max.content.load.filesize to edit. </p>
  
  <p>When I click Help | Edit Custom Properties in Intellij, it says " File '~/Library/Preferences/IdeaC2018.3/idea.properties' does not exist. Create?" </p>
  
  <p>When I create the file and add "idea.max.intellisense.filesize=2500" and  "idea.max.content.load.filesize=20000", it has no effect. In fact, I am getting typo errors. </p>
  
  <p>I have also seen <a href="https://intellij-support.jetbrains.com/hc/en-us/articles/206544869" rel="noreferrer">https://intellij-support.jetbrains.com/hc/en-us/articles/206544869</a> , and I also have no IDE_HOME directory. </p>
  
  <p>I am not sure how to approach from here, can anyone help?</p>
  
  <p>Thanks.</p>
