title: E212: Error Cannot open file for writing (VIM - .startup extension)
body: <p>I have look through various responses to similar questions but none of the solutions have helped me.</p>
  
  <p>I am getting the error:</p>
  
  <blockquote>
    <p>"/pc1.startup" E212: Cannot open file for writing</p>
  </blockquote>
  
  <p>I understand you cannot open a .startup file in notepad and edit it then save it as the .startup extension but I am struggling with finding a way to write the changes to my hard drive. Nano also gives me the same issue. If anyone knows any solutions that would be appreciated.</p>
